Abstract: It is known that the proper orthogonal
decomposition (POD), which is one of the effective approaches for model
order reduction (MOR), can effectively reduce computational time for finite
element method (FEM). This paper proposes a new method for generation of
equivalent circuits based on POD-based FEM. In this method, the circuit
parameters are determined by genetic algorithm so that the input impedance
of the equivalent circuit is coincident with that computed by POD-based
finite element method (FEM). For test of the proposed method, POD-based FEM
is applied to analysis of a dipole antenna which is loaded with the
Cockcroft Walton circuit. It is shown that this method can reduce the
computational time to generate the equivalent circuit without deterioration
of accuracy.
