Simulation Driven Innovation – Changing the Role of Simulation in the age of Internet of Things and Autonomous Driving
Abstract & Bio

The ability of a company to thrive in today’s economy depends on new and innovative products. Profitable enterprises require a constant stream of creative ideas moved into products to win new customers and satisfy existing customers’ needs. In the ideation phase, when the freedom to create and modify a design is at its peak and risk is low, creative use of computer-aided engineering can enable quantification of design performance based on the concept. This supplants subjective decision making and may lead to better product outcomes. Computational techniques become tools for requirements-based design creation rather than merely tools for performance assessment. Eventually, this will lead to a more efficient design process which will produce more innovative products.

In the age of Internet of Things (IoT) and autonomous driving with antennas and sensors embedded in every product, multi-physics simulations and optimization that include antenna and sensors is increasingly becoming a necessity. Computational electromagnetics have matured over the past three decades to become industry standard and hence reducing extensive testing and lowering the cost. Simulations are also playing significant role in design of test facilities and verification of measurement errors via virtual testing in general, and virtual test drives for automotive industry in particular.

In this talk, Dr. Schramm will provide current state of the art multi-physics simulations that span over wide range of products. And will address simulation technologies that are helping improve measurement process in multiple disciplines.

Dr. Uwe Schramm is the Chief Technical Officer for Altair’s solvers, optimization and smart multi-physics solutions and strategy. Beyond developing computational engines for speed and accuracy to solve today’s most complex engineering problems, his organization is committed to developing and deeply embedding optimization technology throughout Altair’s software portfolio to spur innovation and to drive the design process.

Holding senior management positions at Altair over the past 21 years and globally recognized for his research contributions in structural and multi-disciplinary optimization, Dr. Schramm brings a unique blend of deep technical and business management expertise to his role as CTO.

Ultra-Wideband Arrays with Low Cost Beamforming Back-Ends
Abstract & Bio

Future communication links will require higher data rates, multiple beams, and higher transmit/receive gains, in addition to smaller weight, cost, and power. With the growing interest for reduced size platforms and requirement for ultra-wideband (UWB) performance to address multi-functionality, there is also a need for apertures with increased spectral efficiency, multi-functionality and security, spatial multiplexing, and concurrent beams at different frequencies, up to millimeter bands. UWB arrays can also achieve secure communication using long codes that spread across the bandwidth. An added feature is the capability for simultaneous transmit and receive (STAR) applications.

In addition to challenges in designing small size UWB apertures, traditional antenna arrays are associated with complex electronic back-end, typically associated with large power requirements. However, to date, there is no technology for low power and small form factor wideband beamforming. In fact, traditional beamformers are mostly suited for narrowband or multiband operation with inherently high power requirements.

In this presentation, UWB arrays with low-power and low-cost beam forming hardware are presented. Key features include: 1) 10:1 bandwidth with high isolation dual-pol antenna arrays, 2) on-site coding to reduce analog to digital and digital to analog converters by more than an order of magnitude, 3) signal spreading to achieve as much as 40dB of additional processing gain, and 4) 1000 MHz bandwidth with simultaneous transmit/receive capability. At the conference, we will discuss system evaluation and performance of these concepts using simulations and model measurements.

Aerospace to Automotive: The Unique Challenges of Automotive Antenna Design and Test from the Perspective of a Former Aerospace Engineer
Abstract & Bio

Not that long ago, automotive antennas primarily consisted of AM/FM antennas with the occasional TV Antenna. These simple but well performing mast antennas or in-glass designs were the only visual evidence of radio communications on vehicles. However, in the last few years an additional type of automotive antenna has become more visible on the exterior of vehicles. These shark-fin antenna or its smaller puck type associated antennas have rapidly proliferated to the point of becoming a status symbol of luxury automotive brands and even appearing on lower tier models. But outside of a casual interest in the wondering why these plastic covers exist on the roof of their cars, the average customer does not put much thought into the content or function of these antennas. I can attest that as an antenna engineer for an aerospace company I did not put much thought into the content or function of automotive antennas or have any appreciation of the challenges of the automotive industry. Having now working several years as an Automotive Antenna/RF systems engineer, I realize how automotive connectivity and autonomy is resulting in a rapid growth in on vehicle wireless communications and sensing systems. This growth ranges from mm wave radar arrays, GPS/Satellite Radio antennas, multiple Bluetooth, Wi-Fi and cellular MIMO antennas, low frequency antennas for keyless entry, passive entry, tire pressure monitoring, garage door openers, toll plaza antennas through recently added vehicle to vehicle communications antennas and upcoming 5G technology. The result of this growth is that there are unique challenges that must be solved quickly. My experience as an aerospace engineer has prepared me for some of these challenges but others need solutions that are more a fusion of telecommunications and aerospace techniques. At the simplest level these challenges can be scoped as simply upscaling a smart phone to automotive scale. Unfortunately, what sounds simple is much more complex. Existing specifications and test capabilities for smartphones do not take into the unique characteristics or scale of the automotive environment. Adding in the automotive EMC environment and that there are functions that exist in automotive that do not exist in telecommunications creates a significant spectrum management and coexistence challenge. All this must also consider that automobiles are a mature product so these systems must fit in the styling, number of variants and costs that are expected of the industry. In this talk, various challenges and solutions for automotive antenna design, installation and measurements will be presented and future challenges will be discussed.

Antennas enabling mmW/THz Sensors, Communications, Imaging and Metrology
Abstract & Bio

High-speed, ubiquitous wireless networks are beginning to be deployed to form the backbone of next generation wireless connectivity. To realize the overarching goal of anytime-anywhere-anything-“anybaud” connectivity, the 5th generation (5G) networks must be able to sustain much higher bandwidths, leading to the immediate utility of the millimeter-wave (mmW: 60-300 GHz) bands. To effectively address this need, agile antennas and beamforming arrays, as well as wideband transceivers and digital/analog converters have been a focus of concerted research in the past decade. In parallel, development of high-speed diodes, transistors, integrated circuits (ICs) and on-chip antennas benefited many scientific, commercial, and military applications, ranging from spectroscopy, standoff imaging, and non-destructive evaluation; utilizing the sub-millimeter-wave (300 GHz-3 THz) band.

In this talk, we will summarize the research activity at the Ohio State University HELIOS Laboratory spanning the mmW and THz band applications. Particular focus will be devoted to antennas as the key enabling components in such applications. Namely, we will first present a real-time THz camera that has antenna-based focal-plane-array pixels that are impedance matched to the sensor device and concurrently can correct for optical aberrations. The design and characterization of this camera, which is capable of imaging in 600GHz-1.2THz, incorporates electromagnetic/optical modeling and hardware measurements.

We will next underline the utility of on-chip antennas in enabling non-contact device and IC characterization for the entire 50GHz-1.1THz band. Non-contact probing is a novel alternative to device characterization using contact probes. We will show that with the help of specially-designed antennas, the high-cost, fragility and wear-and-tear of contact probes can be eliminated entirely. Moreover, on-chip balun-tennas enable -for the first time- pure-differential-mode on-wafer characterization well beyond the current state of the art 110GHz.

Time permitting, we will conclude with a novel, on-wafer implementation of tightly-coupled current sheet arrays for mmW applications, enabling wafer-scale fabrication of such low-profile arrays, ideal for addressing 5G applications in a cost-effective way.
