Accurate numerical analysis of the truncated elliptic lens

Abstract

The Muller integral-equation (MIE) technique is used for the analysis of the focusing properties of the truncated elliptic lens modeled by a smooth dielectric cylinder characterized with a piece-wise "super-elliptic" cross section. Such a full-wave mathematically correct method guarantees uniqueness of the solution for arbitrary set of parameters. In the discretization scheme, we also use analytical inversion of the canonical circular-cylinder counterpart of the problem and build a very efficient CAD tool. Numerical results for the near fields are presented and lens-focusing properties are studied for the E-polarization case.
