Abstract

The transformation electromagnetics technique provides a powerful tool to electromagnetic and optical designers by offering a blueprint for creating novel devices that feature a variety of unconventional wave-material interaction properties. Combined with the recent advances in metamaterials technology, the coordinate transformation-based design methodology paves the way to realizing devices that perform entirely new functions or traditional functions in different geometrical configurations that are advantageous in practical applications. Here, transformation electromagnetics techniques are applied to the design of invisibility cloaks, lenses, beam controllers, and antennas. Each device design is illustrated with an example, including the associated specifications and performance expectations. For the two-dimensional embedded antenna application, a microwave metamaterial design is also presented.
