The use of an optically modulated scatterer to measure the performance of microwave electromagnetic wave absorber

摘要

The optically modulated scatterer (OMS) can be used to measure the standing wave distribution of microwave electromagnetic fields with minimum intrusiveness. This paper reports the measurement by OMS of a new commercially developed pyramidal ferrite absorber between 2 GHz and 18 GHz. The results are analysed and compared with those by other RF and microwave measurement methods.
