Abstract
This paper shows the application of reciprocity principle in stabilization procedure for finite difference time domain (FDTD) schemes containing locally refined meshes. The method, originally proposed only for verification of stability of FDTD-subgridding algorithms, allows one to change coupling factors between boundary field samples in such a way, that the resulting scheme will be stable. The presented methodology is verified by numerical tests confirm the stability of a modified subgridding algorithm.
