Pseudospectral methods versus FDTD

Stavros V. Georgakopoulos, Constantine Balanis, Rosemary Renaut

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The Chebyshev collocation method is used along with a mapping of the grid to relax the restrictions on the time-step. Entire-domain as well as multi-domain approaches are considered. The accuracy of the spectral methods for all the different approaches is compared with that of the classical second-order finite-difference time-domain (FDTD) scheme. In addition, the CPU time as well as the memory required to achieve certain accuracy are reported for both the spectral and the FDTD methods.
