Abstract :
In order to analyse the scattering properties of the curved electrically large structures with Frequency Selective Surfaces (FSSs) using FDTD algorithm, we propose a modelling way for FSS on curved surfaces, in which cylindrical, conical and spherical surfaces are included, respectively. In this paper, first, the novel modelling way is illustrated in detail, and then, the scattering problems are validated for the mono-static RCS of the curved electrically large structures with FSSs.
