Direction enhancing lens design through quasi-conformal transformation optics

Abstract

In this paper, based on quasi-conformal transformation optics (QCTO), a synthesis design of a conformal array radiation enhanced by an all-dielectric metamaterial lens is presented. For the two-dimensional TE polarization, a physically cylindrically conformed patch array can acquire the same radiating features of a virtual planar focusing patch array, using a lens having only nonmagnetic medium parameters. Full-wave simulations are performed to justify the design approach.
