Verifying the Results of Thin Dielectric Plate Analysis Using Mom-SIE with Approximate Integral Solution

The problem of analyzing the scattering properties of dielectric structures is always a difficult task due to its complexity. Many different modelling techniques have emerged to solve this problem, one of which is the use of the method of moments combined with the surface integral equation to analyze homogeneous dielectric structures. Such analysis is considered in this paper. We proposed the use of the method of moments and the surface integral equation with approximate integral solution instead of the direct one. The formulas derived here for such analysis are described and a MATLAB computer code based on them is developed to analyze thin dielectric plate excited by a TE-polarized plane wave. The results of the analysis of dielectric plates excited by plane waves with TM and TE polarization obtained using the developed code are verified by comparison with numerical results obtained in other publications. The good agreement between the compared results proved the efficiency of the developed code and also confirmed the correctness of using surface integral equation and the method of moments with approximate integral solution for analyzing homogeneous dielectric structures.
