This article presents the design, construction and analysis of a 3D-printed transformed
hyperbolic flat lens working on the 30 GHz band. The transformed lens was printed using …

A flat wideband lens antenna operating in the Ka band is presented. The design
corresponds to the transformation of a hyperbolic lens via quasi-optic transformation into a …

In this work, we present a new systematic technique for the design of a flat lens using
modified commercial off-the-shelf (COTS) materials, as opposed to metamaterials (MTMs) …

Quasi-conformal transformation optics is applied to design electromagnetic devices for
focusing and collimating applications at microwave frequencies. Two devices are studied …

In the last decade, a technique termed transformation optics has been developed for the
design of novel electromagnetic devices. This method defines the exact modification of …

Luneburg lenses have superior performance compared with conventional lenses made of
uniform materials with specially designed surfaces, but they are restricted by the difficulty of …

A zone plate lens utilizing a refractive instead of diffractive approach is presented for
broadband operation. By utilizing transformation optics, we compress the conventional …

A 2-D generalized Maxwell fish-eye lens has been fabricated with all-dielectric
polymer/ceramic composite materials and evaluated numerically and experimentally. The …

The transformation optics technique for designing novel electromagnetic and optical devices
offers great control over wave behavior, but is difficult to implement primarily due to …

This letter proposes a technique for designing flat lenses using field transformation (FT), as
opposed to ray optics (RO) or transformation optics (TO). The lens design consists of 10 …
