Design of sandwich type radomes with Green´s function method as a radiation problem solving

The Green´s functions of layered structures are used for the reflection and transmission analysis from antenna radomes. The incident wave is associated with equivalent surface electric and magnetic currents on the illuminated side of the ra-dome. Reflecting and transmitting fields are calculated as the radiation of equivalent currents. Stratified structure is modeled with equivalent circuit approach. Reflection and transmission coefficients are calculated for different structures, incidence angles and polarization. The application of suggested method to analysis of electrically large antenna radomes is described.
