Summary:
An integro-difference time-domain (IDTD) method, which is based on the integral form of Maxwell’s equations, has been recently developed to achieve 4th order accuracy in space and time by taking into account the spatial and temporal variations of electromagnetic fields within each computational cell. The IDTD method maintains the same numerical structure and Courant-Friedrichs-Lewy (CFL) stability criteria as the conventional second-order FDTD method. In this paper, we present the unique features of IDTD and some numerical results that demonstrate the higher order accuracy and superior dispersion properties of the IDTD method.
