摘要: This paper presents an efficient implementation of spectral-element methods (SEMs) for the analysis 2-D wave guide components with sharp edges. The well-known problem ill conditioning mass matrix when very high-order polynomial basis functions are augmented singular is addressed. A numerical process definition a set orthonormal entire-domain boundary-adapted incorporating relevant edge conditions presented. These synthesized by applying value decomposition algorithm to different sets weighted Chebyshev polynomials. application method both E- and H-plane edges irregular shapes reported. Comparisons various experimental data show that exponential convergence, typical SEMs, achieved.
