Abstract

Gradient-index (GRIN) optics has seen a renewed interest due in large part to the development of Transformation Optics (TO). TO enables the electromagnetic behavior of simple and conventional structures to be replicated by arbitrary geometries. Variations on traditional TO, such as quasiconformal Transformation Optics (qTO), have been developed to enable coordinate mappings to be realized with all-dielectric materials allowing for the method to be readily applied in practical GRIN lens design. However, a number of challenges arise when considering transforming traditional optical elements including replicating multi-frequency behavior and the realization of multi-element transformations. To this end, an alternative transformation procedure based on a wavefront matching (WFM) method has successfully been applied to a number of lens transformations in the optical regime. Finally, by having a suite of electromagnetic transformation procedures available, engineers are able to tackle a wide range of RF and optical problems that require or can benefit from electromagnetic wavefront manipulation.
