Propagation of electromagnetic (EM) wave through a meta-material having anisotropic permittivity and permeability tensors is simulated through Finite Difference Time Domain (FDTD) simulations using a technique of transformation optics. Details of the algorithm used in the simulation are given here. Using the simulation code developed, a two-dimensional dual-purpose polarization-sensitive meta-material is designed and demonstrated. Such a material can perform two independent tasks simultaneously for Transverse Electric (TE) and Transverse Magnetic (TM) polarization. All-dielectric design for TM polarization is also proposed and demonstrated to reduce the constrains on physical realization of such materials.
