Abstract

We present an iterative, unconditionally stable locally-one-dimensional (LOD) finite-difference time-domain (FDTD) method based on the use of an iterative fixed-point correction to reduce the splitting error. Numerical examples are used to illustrate the gain in accuracy of the proposed method versus the conventional LOD-FDTD method and the improved computational efficiency versus the iterative alternating-direction-implicit (ADI)-FDTD method.
