The finite-difference time-domain (FDTD) method has been widely used for solving various types of electromagnetic problems such as anisotropic and nonlinear problems. The FDTD method provides accurate predictions of field behaviors. In this paper, a new algorithm for two-dimensional (2-D) finite-different time-domain (FDTD) is presented in order to increase the maximum time step size and reduce the simulation time by simulating in parallel computation.
