Abstract :
A time domain Haar-wavelet based modeling technique has been applied to 2-D waveguide problems including discontinuities. The principal original contribution of this paper is the correction of the field singularity at the edge of a conductor by quasi-static field approximation. Combination of quasi-static correction and wavelet modeling considerably improves the computational efficiency compared to conventional time domain analysis techniques.
