Elliptical Generalized Maxwell Fish-Eye Lens using Conformal Mapping
New Journal of Physics
A circular graded index lens is conformally transformed to an elliptical shape using a closed-form transformation. The proposed transformation is then employed to compress a Maxwell fish-eye and its generalized version. Since the transformation is conformal, the electromagnetic properties of the device are perfectly preserved after the transformation with fully isotropic and dielectriconly materials. Ray-tracing and full-wave simulations are carried out for several cases to verify thedoi:10.1088/1367-2630/ab2471 fatcat:k43obstkrbbjxkstfhmyz2ozzy
