Design Criteria for Cost-Effective Broad-Band Absorber-Lined Chambers for EMS Measurements

The problem considered here concerns simulating the electromagnetic environment for electromagnetic susceptibility (EMS) measurements over a wide frequency range. Means of bridging the existing gap between low-and high-frequency techniques are suggested by extending the use of anechoic-type chambers downward in frequency. Results of measurements over a wide frequency range are presented to demonstrate the behavior of such absorber-lined chambers (ALC's). Basic criteria and guidelines for the design of ALC's are proposed.
