Abstract :
In this paper, a two-dimensional FDTD technique is presented to solve scattering problems involving PEMC boundaries. Basically, new FDTD updating equations are introduced to realize the PEMC boundary condition. To achieve the formulation, a modified Yee´s Cell at the PEMC boundary is proposed. Next, the method is validated by simulating scattered fields from a PEMC square cylinder and comparing results for two special cases of PEC and PMC cylinder.
