Evaluation of Capacitance of Conducting Bodies for Electromagnetic Modeling

This paper represents the evaluation of capacitance of different conducting bodies are calculated using finite element method (FEM). There are different numerical methods like Finite Difference method, Method of Moment and Monte Carlo methods. But the finite element method has more advantages. The surfaces are discretized using triangular subsections. Finite element method is a suitable method for computation of capacitance in metallic surface. The accurate estimation of electrical parameters is essential for Electromagnetic modeling and Antenna design. In this paper, capacitance of the square plate, rectangular plate, elliptical plate and circular plate are computed using finite element method. For simulation COMSOL multiphysics software was used. FEM is suitable and efficient method for computation of electrical parameters. We evaluate some of our simulation results with other available results in the literature and good matching the results.
