Abstract :
The finite-difference time-domain (FDTD) method is proposed as a means of accurately computing electromagnetic scattering by an external plane wave. The total-field/scattered-field (TF/SF) formulation resulted from attempts to realize a plane-wave source that avoids the difficulties caused by using either hard sources or the initial-condition approach. It is very complicated to get the closed form of the incident fields with ground for a pulse plane wave. In this letter, we carry out the formulations of TF/SF boundary with the ground for the cylindrical FDTD. Numerical examples verify that the presented method can solve the incident wave with ground conveniently and accurately.
