Abstract :
The finite-difference time-domain (FD-TD) method in spherical coordinates is introduced and utilized to simulate electromagnetic fields inside a concentric conducting spherical cavity. A stability criterion and analysis are also presented. Finally, some numerical results of mode patterns inside the cavity are illustrated and compared with analytical solutions.
