Designing three-dimensional transformation optical media using quasiconformal coordinate transformations.
Abstract
We introduce an approach to the design of three-dimensional transformation optical
(TO) media based on a generalized quasiconformal mapping approach. The generalized
quasiconformal TO (QCTO) approach enables the design of media that can, in principle,
be broadband and low loss, while controlling the propagation of waves with arbitrary
angles of incidence and polarization. We illustrate the method in the design of a
three-dimensional carpet ground plane cloak and of a flattened Luneburg lens. Ray-trace
studies provide a confirmation of the performance of the QCTO media, while also revealing
the limited performance of index-only versions of these devices.
