N2 - Anti-aliasing technique based on the oversampling method of rasterization has been introduced to improve FDTD simulation accuracy of 1D, 2D and 3D objects and systems. The method is based on the reduction of an error that happens in the computation during the sub-cell media transitions at dielectric boundaries by calculating an optimal value of the electrical parameters such as dielectric permittivity constant and conductivity for cells at media transitions. The formulation has been developed and implemented in the simulation of 1D,2D, and 3D objects. FDTD simulation results have been presented using the method developed and compared to simulations without implementing this method. It has been shown that the error is drastically reduced with the implementation of the anti-aliasing technique based on the method of rasterization presented in this paper.
