摘要:

AbstractA method is presented to calculate the eigenvalues of the Helmholtz equation Δ2ø +k2ø = 0 in a two‐dimensional area when ø vanishes on the boundary. The method is based on an integral equation, which can be easily solved numerically. Results obtained for circular and rectangular geometries are also given and compared to the exact v
