Abstract

The electromagnetic properties of wire medium are studied by analyzing its transmission coefficient, and a homogeneous uniaxial effective permittivity tensor with one spatially dispersive component is obtained. In order to evaluate the validity of the equivalent model for scattering problems, the bistatic and monostatic radar cross sections (RCS) of a block of wire medium are investigated with the finite-difference time-domain (FDTD) method. The difference of RCS from the physical wire medium and the corresponding equivalent model has been compared and analyzed under various parameters of wire medium, which clearly demonstrates the accuracy of the equivalent model of wire medium.
