Electromagnetics in Novel Isotropic Media

Basic relations of electromagnetic fields in bi-isotropic media are briefly discussed. Such media are more general than the ordinary isotropic dielectric and magnetic media because they can couple electric and magnetic polarizations. Bi-isotropic media have interesting possible applications and the main problem today lies in the fabrication, which has not yet reached an industrial level. However, before starting making such media, their usefulness must be shown theoretically.
