This article takes a look at metamaterials in electromagnetics from a general point of view. The terminology of complex electromagnetic materials is discussed critically. A unique definition for metamaterials does not exist, but certain salient points can be distinguished in the ongoing discussion within the research community and in various formal suggestions for this definition in the literat...

An overview of the transformation electromagnetics/optics design technique is presented. Illustrative example designs for invisibility cloaks, beam control devices, lenses as well as applications to radiation problems are shown. Quasi-conformal transformations in two dimensions and their applications to cloaks and virtual arrays are discussed.

The Maxwell equations constitute a formalism for the development of models describing electromagnetic phenomena. The four Maxwell laws have been adopted successfully in many applications and involve only the integer order differential calculus. Recently, a closer look for the cases of transmission lines, electrical motors and transformers, that reveal the socalled skin effect, motivated a new p...
