Outline of Final Research Achievements

Circuit simulations which consider electromagnetic effects of circuits are required for the physical designs. Conventional electromagnetic analysis lacks flexibility to circuit simulations. Conversely, even if a circuit analysis which expresses the electromagnetic field as circuit elements is used, we cannot observe the electromagnetic field so that it is a fault of this scheme.
To resolve these problems, we examine the mixed analysis from various points of view. For example, vector and scalar potentials are introduced, and volume of nonlinear circuit elements is considered. As a result, a new method for treating circuit elements in electromagnetic analysis is proposed. Based on this method, the circuit simulator and FDTD method, which is well-known as a numerical electromagnetic analysis, are combined. We confirm that the mixed circuit and electromagnetic analysis can be efficiently carried out without loss of flexibility to both analyses.
