Abstract :
The impedance method is an electromagnetic simulation method for quasistatic problems. It is based on the discretization of object(s) upon which electromagnetic radiation is incident, and it requires solving a system of equations in which the number of equations is determined by the number of grid cells in the discretized model. We investigate the feasibility of employing a grid generation method that does not yield equal-sized cells everywhere, as a means of decreasing the size of the linear system to be solved. We apply the method to a simple test case for which analytical results are available, and examine the accuracy and computational efficiency of our method with respect to the standard uniform grid.
