Electromagnetic Scattering for Complex Shape Objects with and without Cloaking

The problem of scattering electromagnetic field modeling on complex objects with and without using radio absorbing coating is considered. Based on existing methods field calculating for complex shape objects and elementary facets a computer program has been developed. It takes into account the field scattered by smooth part of the object, by edges, re-reflections between different parts of the object and contribution of cloaking. The proposed approach allows effectively calculating the field for complex shape objects with different radio absorbing coating without updating the geometric model of the object. The simulation results for elementary targets are compared with the theoretical data for the field scattered by these objects. The developed method results matches with the theoretical data.
