Abstract
A thin film microwave absorber is proposed using a ferroelectric/rubber composite (FRC) structure. The FRC structure consists of a lead zirconate titanate ferroelectric ceramic powder and a rubber composite. The operational principle and experimental results are discussed. A microwave absorber was obtained experimentally with a 1.65 mm thickness, yielding a bandwidth of 480 MHz at a central frequency of 8.6 MHz and analyzed theoretically.
