ADI-MRTD Algorithm for Periodic Structures Analysis

الملخص EN

In this paper, a novel algorithm based on the alternating direction implicit (ADI) multiresolution time-domain (MRTD) method for periodic structure simulation is proposed.

By applying the multiresolution analysis in accordance with wavelet theory, the spatial sampling rate of the conventional finite-difference time-domain (FDTD) is significantly reduced by the MRTD method.

The ADI method is then used to remove the Courant-Friedrich-Levy (CFL) limit that the MRTD method experiences.

The periodic boundary condition (PBC) is directly implemented in the time domain using a constant transverse wave-number (CTW) wave.

Numerical results are presented to confirm the efficiency and accuracy of the proposed method.
