In line with it, the eigenvalues of a geometrical parameter (GP) are calculated instead of the eigenfrequencies resulting in substantial acceleration of the analysis and improvement of the design efficiency. To formulate the eigenvalue problem, the accelerated coupled-integral-equations technique and the Galerkin method with weighted Gegenbauer polynomials as basis functions are applied.en1531-130920045240242CavityEigenfrequencyEigenvalueGalerkin methodTechnikJournal Article10.1109/LMWC.2004.827833Other
