Deduction calculation method for equivalent electromagnetic parameters of rubber plate type wave-absorbing material

Abstract

The invention belongs to the technical field of computational electromagnetism, and particularly relates to a deduction calculation method for equivalent electromagnetic parameters of a rubber plate type wave-absorbing material. The method comprises the following steps of introducing a theory that the volume ratio is consistent and the magnetic conductivity is consistent and a Maxwell Gardt mixed formula into the electromagnetic parameter calculation of the rubber plate type wave-absorbing material, and combining a reflectivity calculation formula to quickly obtain the electromagnetic parameter of the corresponding rubber plate type wave-absorbing material according to the obtained electromagnetic parameter of the corresponding substitute. The manufacturing period of the mixed substitute of the paraffin and the absorbent is shorter than that of a rubber plate, so that the process of manufacturing the rubber plate is omitted, and the problem of long time consumption for obtaining the electromagnetic parameters of the rubber plate type wave-absorbing material in the process of preparing the rubber plate wave-absorbing material in the prior art is solved. Compared with the prior art, the method provided by the invention shortens the manufacturing time of the rubber plate material object.
