Advances in the Design of Anechoic Chambers for Modern Military Vehicles

Abstract: This presentation provides the latest information on chamber design considerations for today's increasingly sophisticated military vehicles. It aims to provide information so a user can understand the limitations of absorbers, chamber design tradeoffs, and test methods to validate the performance goals. The presentation is divided into three parts for anechoic chamber designs for military vehicles. The first part addresses chamber designs for EMC applications typically specified in MIL-STD-461. A brief introduction is provided on the requirements of the standard regarding the chamber design. The second part concentrates on anechoic chamber designs for antenna or radar measurements. Basic design and performance guidelines are presented, and test requirements are discussed in terms of the Free-Space VSWR method, which are typically used for these chambers. The third part of the presentation deals with absorber power handling for high power applications, which are often encountered in military vehicle measurements inside an anechoic chamber. Many of the design concepts and test methods presented also apply to test chambers for electric and autonomous vehicles.

Biography: Zhong Chen is the Director of RF Engineering at ETS-Lindgren, located in Cedar Park, Texas. He has over 20 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 ANSI ASC C63® committee and Chairman of Subcommittee 1 which is responsible for the antenna calibration and chamber/test site validation standards. He is chairman of the IEEE Standard 1309 committee responsible for developing calibration standards for field probes, and chairman of the IEEE Standard 1128 committee for absorber measurements. His research interests include measurement uncertainty, time domain measurements for site validation and antenna calibration, development of novel RF absorber materials, and anechoic chamber designs. Zhong Chen received his M.S.E.E. degree in electromagnetics from the Ohio State University at Columbus. He may be reached at zhong.chen@ets-lindgren.com.

Tutorial Speakers


24TH OF MAY - 9-30AM TO 12-30PM

Mr Craig Denton & Mr Mike Hatfield

Reverberation Chamber Basics

In this tutorial we will provide a theoretical and practical introduction to the reverberation chamber test methodology. The reverberation chamber is unique in its functionality and is applicable to a broad range of uses within the EMC community. This tutorial will cover the basics of the theory behind a reverberation chamber, how to calibrate a reverberation chamber, and how to conduct susceptibility and emissions testing within a reverberation chamber.

Topics to be covered include:

  • Introduction to Reverberation Chambers

  • Reverberation Chamber statistics

  • Tuner effectiveness

  • Chamber rise/fall time characterization

  • Susceptibility testing

  • Emissions testing

  • Shielding testing


24TH OF MAY - 1-30PM TO 4-30PM

Dr Paul Kay and Dr Kevin Goldsmith

This tutorial will provide an overview of RADHAZ and an update to the changes to the AS/NZS 2772.2 that were submitted to the Standards Australia committee TE-007, which have since been accepted in the standard and now appears at Annex E of the 2016 version, which is widely used in Defence and industry.


24TH OF MAY - 9-30AM TO 12-30PM

Dr Bob Scully

This tutorial will look at aspects and details of fundamental shielding theory as based on Schelkunoff’s approach, including discussion of magnetic shielding and engineering design considerations.


24TH OF MAY - 1-30PM TO 4-30PM

Dr Franz Schlagenhaufer and Dr James Buchan

Computer simulation has become a powerful tool in understanding and predicting the electromagnetic behaviour of devices and systems. This tutorial aims at an audience, not just performing the actual work, but also responsible for initiating and managing major modelling projects. What are the benefits of computer simulation, how reliable are the results, how can results be validated, what part plays the interpretation of results? That are the main focal points of the presentation.


The tutorial will cover:

  • selection of a suitable simulation method;

  • preparation of the simulation model;

  • validation of simulation results;

  • post-processing and presentation of simulation results.


The presentation will include some real-life examples for illustration.


24TH OF MAY - 9-30AM TO 12-30PM

Mr Zhong Chen

This tutorial will discuss the theory and applications of the electric field probes, and calibrations methods.  The presentation will discuss the influencing factors of the measurement uncertainties from the calibration process as well as the during the end use, and practical considerations on how to reduce the effects.
