摘要: The method of modal expansions is a fundamental technique for solving the electromagnetic boundary value problems. As its practical alogrithm, point-matching has been used but frequently failed. A new computer-aided procedure based on presented and applied to scattering from periodic structure composed perfectly conducting surface. an example, grating with sinusoidal height profile calculated. It demonstrated numerically that leads desirable results, while does not. Several physical characteristics reflection including diffraction anomalies are explored.
