CEDAR PARK, Texas, July 3, 2009 – ETS-Lindgren engineers will present in several technical sessions scheduled during the 2009 IEEE International Symposium on Electromagnetic Compatibility (EMC 2009) in Austin, Texas over August 17-21. The annual symposium is the premier gathering of EMC engineers from industry, academia and government organizations and attracts over 2,000 attendees from around the world. As a regular contributor to the symposium's technical program and, given the symposium location near ETS-Lindgren's headquarters in Cedar Park, this year the company is especially involved. In addition to ETS-Lindgren engineers sharing their expertise on the technical program, ETS-Lindgren will also host the annual workshops of the ANSI ASC C63® committee and lead a technical tour of its expansive 145,000 sq ft facility and ISO 17205 certified open area test site, the industry's first A2LA-accredited calibration site. Several members of ETS-Lindgren's staff actively participate on the symposium organizing committee.
Since antennas and probes are an important part of the majority of EMC tests, ETS-Lindgren's Senior Principal Design Engineer Zhong Chen returns once again as chair of the popular “Practical Radiated Measurements using Antennas and Field Probes – Fundamental and Advanced Topics.” This full day tutorial provides an introduction to antenna and probe theory addressing applications relevant to EMC. Invited speakers include Dennis Camell of the National Institute of Standards and Technology (NIST), Michael Windler of Underwriters Laboratories (UL), Thorsten Schrader of Physikalisch-Technische Bundesanstalt (Germany), Werner Schaefer of Cisco Systems, and Vince Rodriguez of ETS-Lindgren. Basic topics will be addressed in the morning, with advanced topics presented in the afternoon. Presentations will review related standards activity, uncertainty evaluations of antenna and probe calibrations, time domain methods for antenna calibration and usage, system integration, and instrumentation considerations in antennas and probes applications. The implications of the antenna characteristics on EMC testing will also be discussed including the nature and use of antenna factors, gain, radiation resistance, VSWR, etc.
Dr. Vince Rodriguez, ETS-Lindgren's Senior Principal Antenna Design Engineer, will chair the tutorial “International Advances in Site Validation Techniques and Related Measurement Activity above 1 GHz.” Invited speakers include Michael Windler of UL, Bob Johnk of the Institute for Telecommunication Sciences, Werner Schaefer of Cisco Systems, James Young of Rohde & Schwarz, and Tim O’Shea of Northwest EMC. The purpose of this tutorial is to educate engineers on the recent activity in ANSI ASC C63® and IEC/CISPR developing new procedures for validating EMC radiated emission test sites above 1 GHz. Measurement methods and test instrumentation above 1 GHz will be reviewed with an introduction provided to the validation techniques that are likely to be required in the near future. EUT test setup, selection of a test facility, test instrumentation, and other challenges in product compliance testing above 1 GHz will be addressed. Rounding out the ETS-Lindgren technical presentations at EMC 2009, Dr. Rodriguez will present the paper “Recent Improvements to Dual Ridge Waveguide Horn Antennas: The 18 to 40 GHz Horn.” Mr. Chen will present the paper “Examinations of Higher Order Mode Cutoff Frequencies in Symmetrical TEM Cells.”
In the popular “Demonstrations and Experiments” sessions held in the exhibit area, Joe Tannehill, EMC Software Engineer, will present “Automated Test Software.” Dr. Michael Foegelle, Director of Technology Development, will present “Antenna Pattern Measurement”, Dr. Rodriguez will present “Modeling of (i) a Horn-Antenna Array and (ii) a Cassegrain Antenna (Use of Shaped Reflector Dish) to Demonstrate Improved Field Uniformity of RF Immunity Test Fields over 1.0 to 6.0 GHz” and Garth D’Abreu, Technical Manager - RF Engineering Group, will provide technical support to the “Overview and Demonstration of Measurements of Shielding Effectiveness Using IEEE P299.1 Techniques” featuring an ETS-Lindgren SMART™ 1000 reverberation chamber. It will certainly be a busy week for ETS-Lindgren engineers as they share their expertise in designing new solutions for the test and measurement of wireless, microwave, military and commercial products.
