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. ...

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 ...

Here, we demonstrate that by extending the common twodimensional (2D) transformation optics (TO) to the third dimension in an engineered fashion, it is possible to eliminate unwanted reflections from the device boundaries ...
