摘要

An approach to introduction of effective constitutive tensors of the periodic layered systems, based on the approximate calculation of the characteristic matrix of the unit cell with the help of Campbell-Hausdorff series, is used for analysis of the plane stratified bianisotropic structures. These structures can possess gyrotropic (bianisotropic) properties even in a case, when layers are nongyrotropic (form gyrotropy). It is shown that by using the presented approach, the effects of form gyrotropy (bianisotropy) can be explained in terms of the theory of effective parameters. The possibilities of introduction of effective material tensors not dependent on the parameters of incident wave, and also the accuracy of different approximations will be discussed. Previously obtained theoretical results are verified by means of extensive computations of transmission and reflection of plane electromagnetic waves by systems at hand for different planes and angles of incidence.
