© 2014 IEEE. In this paper, nonorthogonal locally one dimensional finite difference time domain (LOD-NFDTD) method based on curvilinear coordinate system is presented for analyzing electromagnetic scattering from curved conducting structures. A formulation of LOD-NFDTD method for two dimensional problems is provided. In our generalized approached, the non-orthogonal grid is used to model the computational domain which is bounded at the far end by a curvilinear convolutional perfectly matched layer (CPML) absorbing boundary condition. Numerical results are presented comparing with results available in the literature for TEz scattering by conducting cylinders.
