Designing Devices for Wave-Vector Manipulation Using a Transformation-Optics Approach

Designing Devices for Wave-Vector Manipulation Using a Transformation-Optics Approach A transformation-optics approach is used to derive a general method for designing electromagnetic devices able to manipulate the wave vectors in the specific manner required by the functionality of the device. While the wave paths inside the device remain of secondary importance, the wave vectors are gradually changed in the desired way by choosing the appropriate coordinate transformation. The proposed method is applied to designing both converging and diverging flat lenses.
