Bianisotropics and electromagnetics

Abstract

Bianisotropics is conceived as a physical concept describing electromagnetic media which possess intrinsic mechanisms of magnetoelectric coupling. We propose the main idea of bianisotropics as a combination of two physical notions: (a) the near-field manipulation and (b) chirality. From classical laws these two notions are in an evident contradiction since manifestation of chirality in electromagnetics is usually due to effects of the field non-locality. In attempts to combine the field locality and chirality in media properties, we come to non-classical aspects, which constitute a subject of a macroscopic quantum mechanics analysis. This opens a new field of studies, which we call as the problem of bianisotropic metamaterials (BMMs).
