These challenges include non-standardized launch veh icle and host interface requirements\, unspecified lightning protection re quirements\, and schedule constraints on EMC testing and development. Tech nical challenges include power and signal isolation\, crosstalk from long pigtails in wire harnesses\, limited physical space for filters and shield ing\, and large apertures in the vehicle faraday cage.\n\nSpeaker Biograph y: Russell Carroll is a consulting engineer with extensive experience in t he analysis\, design\, and testing of electromagnetic effects on units and systems including space satellites and industrial electronics. His resear ch is focused on developing useful analysis tools and methods for unit and system level EMC analysis. Mr. Carroll is a registered Professional Engin eer and an iNARTE certified EMC Engineer. He received the B.S. and M.S. de grees in electrical engineering from the University of Alaska Fairbanks in 2013 and 2014.

By integrating Cylindrical Mode Filter ed Site Voltage Standing Wave Ratio (CMF SVSWR) with Compressed Sensing (C S)\, we address inherent challenges in traditional SVSWR methods\, such as inconsistency and slow data acquisition. CMF SVSWR utilizes circular path measurements and mode domain post-processing to discern antenna and chamb er reflections\, crucial for comprehensive VSWR analysis. Compressed Sensi ng\, a data-driven machine learning technique\, exploits signal sparsity t o reconstruct data from fewer randomly sampled measurement points\, thereb y reducing test times and eliminating the need for precise turntable posit ioning.\n\nSpeaker Biography: Zhong Chen is Chief Engineer at ETS-Lindgren \, located in Cedar Park\, Texas. He has more than 25 years of experience in RF testing\, anechoic chamber design\, as well as EMC antenna and field probe design and measurements. He is an active member of the ANSC C63® c ommittee currently serving as Vice-Chair and is the immediate past Chair o f Subcommittee 1 which is responsible for the antenna calibration (ANSI C6 3.5) and chamber/test site validation standards (ANSI C63.4 and the ANSI C 63.25 series). Mr. Chen is chair of the IEEE Standard 1309 committee respo nsible for developing calibration standards for field probes\, and IEEE St andard 1128 for absorber evaluation. He is a former member of the IEEE EMC Society Board of Governors and the Antenna Measurement Techniques Associa tion (AMTA) Board of Directors. He is a past Distinguished Lecturer for th e EMC Society and is recognized as an AMTA Fellow. His research interests include measurement uncertainty\, time domain measurements for site valida tion and antenna calibration\, and development of novel RF absorber materi als. Several papers authored and co-authored by Mr. Chen have received bes t paper recognition at global conferences. Zhong Chen received his M.S.E.E . degree in Electromagnetics from the Ohio State University at Columbus.

In aerospace EMC testing\, measurements a re typically performed per MIL-STD 461\, which requires only 10 dB attenua tion above 250 MHz—allowing chambers to remain relatively reflective and without system-level validation. Using time-gated antenna reflection meas urements\, we show a practical method to verify and quantify actual chambe r performance.\n\nIf time permits\, we will also demonstrate the Cylindric al Mode Filtered (CMF) technique. This method measures the antenna pattern with an intentional offset (e.g.\, placing the antenna at the edge of the turntable). The complex S21 versus angle at each frequency is transformed into the spectral domain\, where filtering removes chamber contributions mathematically\, producing a “clean” antenna pattern even in a nonidea l environment. For site validation\, standing-wave ripples are obtained by comparing the original chamber pattern to the filtered result. The demo w ill cover the full measurement workflow\, including real-time post-process ing. The CMF SVSWR technique is under consideration in the draft ANSI C63. 25.3 by ANSC C63 and in CISPR 16 site validation standards for EMC test si tes from 18 GHz to 40 GHz.\n\nMANY THANKS TO OUR LUNCH SPONSOR ROHDE & SCH WARZ!!\n\nAgenda: \n1:00 pm - Registration Check-In and Complimentary Lunc h Courtesy of Rohde & Schwarz\n\n1:40 pm - Welcome from Seattle EMC Chapte r Chair\, Janet O'Neil with ETS-Lindgren and Seattle AP/ED/MTT Chapter Cha ir\, Dennis Lewis with Boeing\n\n1:45 pm - EMC Challenges for ‘New Space ’ Small Satellite Development By Russell Carroll\, EMI/EMC Consulting En gineer\, EMI Sleuth\, El Segundo\, CA\, USA\n\n2:30 pm - CISPR and ANSC C6 3® Overview on Site Validation Measurements from 18 GHz to 40 GHz - Lates t Advances in EMC Test Site Evaluation Using Advanced Antenna Measurement Techniques By Zhong Chen\, Chief Engineer\, ETS-Lindgren\, Cedar Park\, Te xas\, USA\n\n3:30 pm - Refreshment Break\n\n3:50 pm - Overview of Boeing E MC Lab and Demo Set Up by Dennis Lewis\, Technical Fellow with Boeing and Zhong Chen with ETS-Lindgren\n\n4:20 pm - Technical tour of the Boeing EMC Lab with LIVE demo\n\n5:00 pm - Adjourn\n\nBldg: 2-122\, Boeing\, 7701 14 th Ave Soutn\, Seattle\, Washington\, United States\, 98108 LOCATION:Bldg: 2-122\, Boeing\, 7701 14th Ave Soutn\, Seattle\, Washington\ , United States\, 98108 ORGANIZER:j.n.oneil@ieee.org SEQUENCE:37 SUMMARY:Seattle EMC and AP/ED/MTT Joint Chapter Half-Day Workshop on EMC an d Aerospace Measurement Challenges URL;VALUE=URI:https://events.vtools.ieee.org/m/536936 X-ALT-DESC:Description: <br /><p><img src="https://events.vtools.ieee.org/v tools_ui/media/display/2e4b8b58-f44f-431a-b689-bcaa14c3902b" alt="" width= "581" height="382"></p>\n<p>&nbsp\;</p>\n<p><strong>TECHNICAL PROGRAM</str ong></p>\n<p><em>This program is dedicated to the memory of Omar Zubi\, Bo eing's longtime EMC Lab Manager\, who passed away suddenly on January 31\, 2026.</em></p>\n<p>&nbsp\;</p>\n<p><strong>EMC Challenges for &lsquo\;New Space&rsquo\; Small Satellite Development</strong></p>\n<p><em>By Russell Carroll\, EMI/EMC Consulting Engineer\, EMI Sleuth\, El Segundo\, CA\, US A</em></p>\n<p><strong>Abstract:</strong><em> </em>This presentation discu sses EMC challenges seen by engineers in the &lsquo\;new space&rsquo\; wor ld of small satellite development.
