Abstract

A new method of multiresolution time-domain analysis is proposed

which is based on Coifman compactly supported scaling functions with some number of vanishing moments.The highly linear dispersional properties of the method are investigated and compared with conventional FDTD method.The problem of scattering from two-dimensional conducting cylinders is analyzed in order to demonstrate the advantages of this method over conventional FDTD scheme with respect to memory requirements and execution time.
