Identifying and Mitigating Radio Frequency Interference

EMA Expo 2024

Jan. 29- Feb. 2, 2024
Denver Marriott West
Golden, Colorado

Course Detail:

This course will present an overview of radio frequency interference (RFI) problems and show how engineers and scientists can use simulation and measurement to identify and mitigate such issues. Finding RFI problems early in the design process prevents loss of major revenue due to product redesign, delayed releases, recalls, and legal battles. To accurately predict and effectively mitigate RFI, engineers need wideband models for all of the components in the RF architecture and wideband antenna-to-antenna coupling data. This course will include examples of real-world problems that have been solved using this approach in addition to measurement demonstrations. At the end of the course, attendees will have a thorough understanding of how to approach RFI problems in the workforce or in research.

The course will include four main sessions:

  • Overview: What is the RFI/Cosite problem and why should you care?
  • Data needed for simulation and analysis
  • Measured data
  • Using simulation to identify and mitigate interference

Instructors will work with attendees to learn about the challenges they face to help find solutions to their problems.

Who Should Attend?

The course is geared toward systems engineers, RF engineers, antenna engineers, avionics engineers, and anyone needing to resolve RFI problems in the design process of their platform or product. The approach the class will take has been successfully applied to military aircraft, autonomous vehicles, satellites, ships, military ground vehicles, commercial space launch systems and platforms, and much more.

Featured Presenters:

Matt Miller, EMA Principal RF Engineer II and Co-Owner

Matt Miller leads a group at EMA providing analysis services for RF interference, installed antenna performance and radar signature prediction. He has 25 years of experience in electromagnetics, business development, marketing, and sales.

Matt worked for The Boeing Company from 1998 to 2001 as an electromagnetic effects engineer supporting various defense and space programs providing analysis in the areas of antenna-to-antenna coupling, electro-static discharge, lightning effects, receiver intermodulation product generation and shielding effectiveness. From 2001 to 2005, he worked for SAIC-DEMACO in Champaign, Illinois as a research scientist performing code development and analysis for various types of electromagnetic phenomena.

In 2005, Matt co-founded Delcross Technologies, LLC where he served as president. Delcross developed commercial simulation tools for cosite interference, installed antenna performance and radar signature prediction. Ansys, Inc. acquired essentially all the assets of Delcross in 2015. Matt joined EMA in 2017.

Juan Arambula, EMA RF Engineer

Juan Arambula is an RF Engineer at EMA focusing on measurement and simulation of radio hardware. Prior to EMA, he designed cellular frequency RF amplifiers with Wilson Electronics for U.S. and Asian markets. In addition, he developed an ATE setup to ensure FCC part 20 compliance, thereby eliminating failures during certification testing.

At EMA, he is the lead engineer for the Automated Radio Measurement System (ARMS), capturing the broadband performance of radios for use in cosite analysis. In addition, he simulates the electromagnetic performance of PCBs and advises designers on any modifications needed for EMI/EMC compliance. Juan earned his bachelor’s degree in Electrical Engineering from California Polytechnic State University. He is currently pursuing his master’s degree from Arizona State University with an emphasis in Electromagnetics, Antennas, and Microwave Circuits
