Method of auxiliary sources applied to thin plates and open surfaces

The results of the efficiency study of the Method of Auxiliary Sources (MAS), applied to the problem of electromagnetic wave diffraction by infinitely thin and perfectly conducting unclosed surfaces, are presented in this paper. Planar, corrugated, hemispherical, and half-open surfaces are discussed. The numerical implementation details, allowing the determination of the induced currents on the different sides of the open surface, are discussed. The numerical results obtained with the MAS are compared to those, obtained with the help of the Method of Moments. It is demonstrated that the MAS has some advantages over other methods, is efficient, and trustworthy for the simulation of such problems. This is confirmed by comparing certain numerical results with the real experiment data.
