Artificial and anisotropic materials for radome construction
Abstract
The paper describes the production of a composite formable board material for radome construction consisting of a polyurethane foam matrix with metallic inclusions to provide controlled permittivity. The artificially loaded material has good mechanical properties at high temperatures (150 C) and can be used as a radome core material. A dielectric material with controlled asymmetry which can be applied to improve the performance of sandwich type radomes by maintaining circular polarization is also described. The core material described consists of a lightweight foam consisting of layers of metallic loading or high permittivity material, and can be molded to the radome shape and is again suitable for use up to 150 C.
