Vector-Based Analysis of Axially Symmetric and Conducting Diffractive Lenses

Abstract

The analysis of diffractive lenses that have feature sizes comparable to the illumination wavelength require a rigorous, or vector-based, model of diffraction. However, most techniques presented in the literature for the vector-based analysis of such elements are limited to two-dimensional (2D), or cylindrical, lenses. In this paper we present a vector-based technique for the analysis of three-dimensional (3D), or spherical, diffractive lenses that are perfect electrical conductors (PEC).
