RISTransformation optics for perfect two-dimensional non-magnetic all-mode waveguide couplers
Here, we demonstrate that transformation optics can be used to produce 2-D
non-magnetic waveguide couplers with no reflections. Our approach consists of using a scaling
function for reflection suppression and introducing an auxiliary...
Design of an optical spatial interferometer with transformation optics
In this paper, we apply transformation optics to design an optical spatial interferometer. The transformation equations are described and two-dimensional finite element simulations are presented to numerically confirm the functionality of the device...
Elliptical generalized Maxwell fish-eye lens using conformal mapping
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. ...
Design of Nonmagnetic All-mode Waveguide Coupler with Perfect Transmission Using Transformation Optics
Using the transformation optics method together with the basic properties of Maxwell equations, a compact nonmagnetic waveguide coupler is designed that can ideally couple all TMn modes. Two compression functions are proposed to provide a perfect...
