Addressing the Increasing Wireless Requirements for Commercial Aircraft and Aerospace Applications

By Mr. Dennis Lewis, Boeing, Seattle, WA


Abstract:  The number of consumer portable electronic devices (PEDs) available are increasing exponentially, as are the number of PEDs finding their way onboard aircraft. This presentation highlights the effort taken by the FAA and RTCA special committee 202 to address this issue. The industry document RTCA DO-307 which was published by this special committee, outlines the requirement for the design and certification of new aircraft to be PED tolerant.  This presentation will discuss the statistical test methods used to ensure aircraft meet the requirements specified in DO-307.  



EMC Test Challenges of Unmanned Aerial Systems - Why Drones Matter to an EMC Test Engineer and Antenna Designer

By Vignesh Rajamani, Oklahoma State University, Stillwater, OK


Abstract:  With the proliferation of Unmanned Aerial Systems (UAS) the national airspace through every possible market, EMC issues can hinder the full potential for widespread civilian use of UAS.  Operational and design barriers include the desirability of rapidly reconfigurable avionics systems that do not require full system recertification, and the adaptation of general aviation EMC standards for UAS applications. Integration of various commercially available systems (COTS) systems on a UAS platform creates unique challenges and inter-operability between systems needs to be ensured for proper operation of UAS. 



State-of-the-art Simulation Techniques for Installed Antenna and RF System EMI Analysis

By Jason Bommer, Delcross Technologies, Seattle, WA


Abstract:  As the number of wireless systems continues to grow and emerge across various industries, there is an increasing need to include radio frequency interference (RFI) and coexistence assessment in early stage design.  Simulation provides an efficient and cost effective complement to prototype testing, and can dramatically improve the design process.  In this presentation we introduce a multi-fidelity approach to RFI characterization.  We highlight a workflow for identifying and mitigating interference using a combination of simulation techniques including physics-based field solvers and system level power envelope models.  This highly flexible approach allows for various levels of data input for defining Tx/Rx spectral profiles, RF components, and antenna characteristics, which all contribute to the RFI assessment.  The system-level RFI analysis is performed across all active channels and may comprise input data derived from various sources including common full-wave solvers as well as test data.    



Use of EMC Reverberation Chambers for OTA testing of wireless devices

By Edwin Mendivil, ETS-Lindgren, Cedar Park, TX


Abstract: Reverberation chambers have been used in the area of Electromagnetic Compatibility (EMC) testing for a long time. With the proliferation of wireless devices in recent years, there has been a lot of interest in extending the reverberation chamber capabilities to measure the radiated power and receiver performance of wireless devices, including Long term Evolution (LTE) 2x2 downlink Multiple-Input-Multiple Output (MIMO) and transmit diversity.  This presentation will show the latest techniques to validate an EMC Reverberation chamber to be used for OTA testing of wireless devices in order to make sure the desired conditions for accurate measurements are met.




Mr. Dennis Lewis has worked at Boeing for 27 years and is recognized as a Technical Fellow. He currently has leadership and technical responsibility for the primary RF, Microwave and Antenna Metrology labs.   He actively contributes to the IEEE and several of its technical societies as a member of the IEEE MTT-S subcommittee 11 on microwave measurements and as a Board Member and a past Distinguished Lecturer for the EMC Society.  He is a Senior Member and serves on the Board of Directors for the Antenna Measurements Techniques Association (AMTA) and chaired its annual symposium in 2012.  Dennis is a part time faculty member teaching a course on Measurement Science at North Seattle College. His current technical interests include aerospace applications of reverberation chamber test techniques as well as microwave measurement systems and uncertainties.


Dr. Vignesh Rajamani received his Ph. D. degree in Electrical Engineering with emphasis on Statistical Electromagnetics at Oklahoma State University and a Master of Science degree in electrical engineering with emphasis on computational Electromagnetics from Oklahoma State University and Bachelors of Engineering degree in Electronics and Communication engineering from the University of Madras. His research focuses on statistical electromagnetics, antenna engineering, RFID, reverberation chamber operations, validation, and EMI/C issues with Unmanned Aerial Systems. His current research focuses estimating probability of failure of electronic systems due to electromagnetic interference and compatibility.  He is the Vice President of Member Services for the IEEE Electromagnetic Compatibility (EMC) Society and involved with several technical committees and educational activities through EMC Society and Oklahoma State University. He is a Senior Member of IEEE and served as a distinguished lecturer for the IEEE EMC Society for term 2013-2014. He has lectured around the world on reverberation chamber test methodologies and has taught design engineering seminars for faculty and students at many universities focusing on challenges in engineering education and to prepare the faculty to handle them by spreading a significant number of Project Based Learning (PBL) classes across the curriculum.


Mr. Jason Bommer is a Senior Application Engineer at Delcross Technologies and has over 17 years of experience in EMC design, analysis and testing.  His current role includes assisting and guiding customers in applying simulation tools for RF EMI assessment, installed antenna analysis and radar signature prediction.  Prior to joining Delcross, Jason served as an electromagnetic effects engineer with The Boeing Company performing roles as test engineer and analyst for a wide range of applications including antenna integration, RF propagation modeling, and wireless performance assessment. 


Mr. Edwin Mendivil is an RF Engineer with ETS-Lindgren, located in Austin, Texas.  He has 15 years of experience in OTA/SAR testing and measurements. Edwin received the B.M.S. degree in signals and telecommunications from Chorrillos Military Academy, Lima, Peru, in 1984, and the B.S. and M.S. degrees in electrical engineering from Florida Atlantic University, Boca Raton in 1994 and 1996, respectively.  His Master’s thesis concerned the performance of ultrawide-band radars under clutter and stealth target environments. In 1996, he joined the Motorola Corporate Electromagnetic Energy (EME) Research Laboratory in Fort Lauderdale, FL, where he was involved in the development of software tools for the analysis and measurement of SAR.  Edwin joined ETS-Lindgren in 2013, working primarily on the design of reverberation chambers.
