| Abstract(in English) | In this study, we consider fast and accurate calculation algorithms to compute double infinite integrals whose integrands consist of trigonometric functions and Bessel functions, appearing in coupling problem with multiple rectangular holes. The integral region is divided into a finite region of maximum radius A and an infinite region outside the finite region, which is further divided into a region where two variables are infinite and two types of regions where only one variable is infinite. We especially investigate integrals in the region where only one variable is infinite. After implementing and validating computational codes for an integration method that combines numerical and analytical methods, we confirmed that we can obtain accurate results in quite shorter time than numerical integration only. |
