Abstract

A multi-layered microwave absorber suitable for use in ships, aircrafts and the like comprises a plurality of layers differing in impedance which are bonded together into an integral sheet structure by a silicone-type adhesive compound applied to a coat thickness of less than 0.1 mm. The absorber is capable of wave absorption over a wide band, free from deformation or distortion, and highly heat-resistant and weather-proof. A method of manufacturing the multi-layered microwave absorber is also disclosed.
