Evaluation of the Computational Efficiency of a Wavelet-Transformed FDTD Scheme

摘要

An evaluation in terms of computational efficiency and accuracy of their scattering parameter in a ID wavelet-transformed FDTD scheme is presented. This scheme combines the favorable characteristics of a FDTD scheme and the possibility to resolve the electromagnetic field on locally different resolutions. Orthogonal and bi-orthogonal wavelets with compact support have been used for the discrete wavelet transform. The Haar wavelet is the best choice in comparison between accuracy of scattering parameter and computational efficiency.
