WAVELET-GALERKIN METHOD IN SOLVING DYNAMIC ELECTROMAGNETIC-FIELD PROBLEMS

This paper presents a wavelet-Galerkin method to solve dynamic electro magnetic field problems. It differs from some former methods which dis cretize the whole space domain using wavelet functions, however it dis cretizes the space domain with finite element, because of its flexibil ity to the boundary. At the same time, it introduces the scaling funct ion as trial functions for time domain, which are space orthogonal alo ng the real line but has poor ability to adapt complex boundaries. Thu s, it corporates both's merits. The results are better without sufferi ng too much calculation time.
