Abstract

An evaluation in terms of computational efficiency and accuracy of their scattering parameter in a 1D 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
