Abstract(in English) | A discretization into a linear system of equation needs an integral over a rectangular element in the two-dimensional volume integral equation method. In a typical computation, one considers a double integral over a square element and uses Richmond's approximation formula. This paper presents a fast and accurate estimation of the double integral. We express a integration point in the two-dimensional polar coordinate system and reduce the double integral to a single one. Here, the 3 types of one-dimensional integral are considered according to the position relation between the square elements for matching and integration. Through some numerical experiments, we determine the number of sampling points for the numerical integration for the reduced one-dimensional integral in order that the accuracy may be satisfied a certain value. |
