Abstract
In this letter, the alternating-direction-implicit (ADI) technique is applied to spectral finite-difference time-domain (SFDTD) method, resulting in an ADI-SFDTD method. It holds the advantages of both ADI-FDTD and SFDTD, not only eliminating the restriction of the Courant-Friedrich-Levy (CFL), but also solving the oblique incident wave on periodic structures conveniently. In order to save the CPU...
