Wavelet Packet Transform with Iterative Technique based on Method of Moments for large-scale problems

Numerical solution of complex electromagnetic problems using hybrid techniques is presented in this paper. By combining the desirable features of the method of moments (MoM) and wavelet packet transform (WPT) to analyze large-scale electromagnetic problems. The computational domain is divided into smaller and manageable sub-domains, with coupling between these sub-domains is taken into account. As a result, a considerable reduction in the computational time and required computer memory storage is achieved.
