Role of Reverberation Chamber in Wireless Testing and Measurement with Emphasis on Investigating Biological Effects

Reverberation Chamber was first conceptualized five decades back but is yet to receive its due recognition in wide area of electromagnetic research. It is an electrically large cavity made of conducting walls through which electromagnetic waves cannot penetrate resulting in high quality factor and effective shielding. Unlike Anechoic Chamber, electromagnetic signal generated inside Reverberation Chamber reflects back and forth multiple times and simulates multipath effect similar to real time scenario; as a consequence, an object inside Reverberation Chamber is expected to be irradiated with electromagnetic waves from different directions along with dissimilar polarizations. Reverberation Chamber has wide applications like figuring out radiated emission and electromagnetic immunity of electronic devices, shielding effectiveness of absorbers, calibrating Radio Frequency probes, characterizing antenna efficiency, dielectric heating and investigating biological effects of electromagnetic radiation. This article aims at highlighting potentials of Reverberation Chamber in electromagnetic research with special emphasis on investigating biological effects of electromagnetic radiation.
