A new modeling procedure for the IE-based non-overlapping domain decomposition method

In this paper, a new modeling procedure for the integral equation-based non-overlapping domain decomposition method (IE-NDDM) is proposed. First the integral equation is established on the entire PEC surface, then the entire surface is partitioned into some non-overlapping open-surfaces (called subdomains). The RWG basis functions are used to expand the equivalent surface electric current on the entire surface. Each full RWG basis function across some boundary curve is split into two half-RWG basis functions. The global MoM matrix equation is then combined with the sparse matrix equation determined by the boundary current continuity to form the complete model equation. Numerical results demonstrate the validity of the proposed method.
