Abstract

The equivalence principle algorithm is introduced in this paper to solve multiscale problems in the electromagnetic modeling of circuit problems. In these problems, low frequency circuit physics coexists with high frequency wave physics that makes the matrix equation ill- conditioned. As a domain-decomposition based algorithm, the equivalence principle algorithm casts the entire domain into di®erent parts based on their physical properties. Each part is solved individually by introduction of virtual equivalence surfaces. Moreover, the interactions among domains are still modeled accurately that captures the electromagnetic wave propagation. With this algorithm and powered up with multilevel fast multipole algorithm, large multiscale problems can be solved on a single computer E&Plusmn;ciently.
