ABSTRACT

Electromagnetic phenomena in bianisotropic media are very rich, and they have been studied in a large number of publications. Bianisotropic media can be classified as chiral and omega media (reciprocal magnetoelectric coupling) and Tellegen and moving media (nonreciprocal coupling). Among reciprocal bianisotropic materials, omega composites have been found of interest with respect to the realization of backward-wave propagation and negative refraction. Bianistropic media exhibit a number of very interesting and practically useful effects, ranging from optical activity to simulating electromagnetic phenomena in moving media. Many of them have been known for a long time and explored in practical devices, both in optics and in the microwave region. Metamaterial technology allows one to realize effects not found in nature, tune the effects for specific applications, and realize strong magnetoelectric phenomena in the optical region. The last challenge requires further development of nanotechnologies, as it requires manufacturing of complex-shaped, three-dimensional, nano-sized structures.
