摘要

The focusing properties of a truncated elliptic dielectric cylinder taken as a 2-D model of a dielectric lens are studied for the plane wave illumination. The Muller integral-equation (IE) technique is used for the analysis of the scattering problem. 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.
