Abstract

The purpose of research is to outline the domain of applicability of the geometrical optics (GO) and physical optics (PO) in the small dielectric lens analysis. As a benchmark solution, we use the Muller´s boundary integral equations (IE) discretized with trigonometric Galerkin scheme that has guaranteed and fast convergence. The lens cross-section is chosen typical for practical applications, namely an extended hemiellipse whose eccentricity satisfies the GO focusing condition. The lens flat side dimension varies between 2 and 8 wavelengths in free space, and its material is rexolite (s = 2.53). We consider the 2D case with an E-polarized plane wave incidence and extract comparison characteristics from the near field analysis.
