Recent trends in the integration of circuit optimization and full-wave electromagnetic analysis

In this paper, we provide an overview of some recent trends for the general electromagnetic (EM) circuit co-optimization approach based on an electromagnetic database (EMDB). This study is the result of long-standing efforts toward the development of an efficient planar EM simulator and its seamless integration in and combination with a circuit design environment. Two complementary techniques are put forward to build an EMDB model. Flexibility, accuracy, and computational efficiency of both techniques are validated by several examples.
