Implementation of TF/SF Boundary for FDTD Method on Face-Centered-Cubic (FCC) Grids

摘要

The implementation of total-field/scattered-field (TF/SF) boundary for finite-difference time-domain (FDTD) method based upon FCC grids was proposed in this paper. The update equations of the electric and magnetic field components on the TF/SF boundary are derived. The effectiveness of the TF/SF boundary is verified by simulating the amplitude distribution of the vertical and oblique incident plane waves in the whole calculation region. This research can provide necessary basis for further analyzing electromagnetic scattering of targets using FDTD method based upon FCC grids.
