使用闭合形式变换将圆形渐变折射率透镜共形地变换成椭圆形状。提出的变换，然后压缩麦克斯韦鱼眼和它的广义版本。由于变换是保形的，所以在利用完全各向同性和仅介电材料进行变换之后，器件的电磁特性被完美地保持。光线跟踪和全波模拟进行了几种情况下，以验证几何光学和波动光学制度的光学变换透镜的功能。
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 dielectric-only materials. Ray-tracing and full-wave simulations are carried out for several cases to verify the functionality of the optically transformed lenses in geometrical optics and wave optics regimes.
