Abstract:

In this paper, structured non-orthogonal alternating direction implicit finite difference time domain (ADI-NFDTD) method based on curvilinear co-ordinate system is presented for analyzing electromagnetic scattering from curved structures. A formulation of ADI-NFDTD method for two dimensional problems is provided. A general procedure for structured nonorthogonal discretization grids into ADI-FDTD is also described. In our generalized approach, the non-orthogonal grid is used to model the computational domain which is bounded at the far end by curvilinear convolutional perfectly matched layer (CPML) absorbing boundary condition. In addition, numerical results are presented with a comparison with results available in the literature for various conducting bodies.
