In this paper, we present a hybrid technique for calculation of frequency-dependent resistance and inductance with method of moments based on Coifman wavelets. The hybrid method combines a cross-section coupled circuit method with a surface integral equation approach. A coupled integral equation is then derived to relate these quantities through the diffusion equation inside the conductors and Laplace's equation outside. The method of moments is used to solve the integral equation. Instead of normal pulse basis, we use Coifman wavelets as expansion and testing functions. By using the one point quadrature technique, the computational time can be reduced greatly while maintaining the accuracy of same level.
