Abstract: The conventional Yee grid modeling approach employed within the unconditionally stable complying-divergence implicit finite-difference time-domain (CDI-FDTD) technique commonly encounters ...
Abstract: A symmetry treatment in cylindrical explicit and unconditionally stable FDTD (CEUS-FDTD) method is given. The system matrix of CEUS-FDTD method is unsymmetric, which will render instability ...
