摘要: This communication describes a method of moments formulation to analyze the scattering from corrugated surfaces. The approach is based on aperture integral equation. Such decouples analysis impedance effect grooves external coupling among and allows us deal accurately with any shape. Advantage taken geometrical properties problem solve it efficiently using conjugate gradient-FFT algorithm.
