概要:

application/pdf<br />Journal Article<br />The eigenvalue problem of Helmholtz's equation is of importance because various physical phenomena are governed by this equation. This paper presents a method for solving the boundary value problem governed by Helmholtz's equation haying a circular outer boundary and a number of eccentric circular inner boundaries. In this problem, it is difficult to satisfy the multiple connected boundary conditions. … The present anlysis uses the point-matching approach for treating the inner boundary conditions, and presents the expression for finding the eigenvalues. Numerical calculations have been carried out for the system having one, two or four eccentrdc circular inner boundaries. 続きを見る
