Anisotropic nonlinear dielectric response of relaxor ferroelectrics

The anisotropy of the nonlinear static dielectric response of inorganic relaxor ferroelectrics of lead magnesium niobate PMN type is studied in the framework of the spherical random bond–random field model. Assuming that the shape of a polar nanoregion PNR and thus its dipole moment is modified by the action of homogeneous lattice strains, the anisotropic part of the interaction between the PNR...

Electromagnetic modeling of anisotropic medium and applications

A stable method of calculation of the electromagnetic response of planar anisotropic laminates to an active source with limited distribution along the strata direction is developed. The laminates can be sandwiched between isotropic, anisotropic, or perfectly conducting covers/substrates. The source is either inside the laminates or in the cover or substrate. Based on the propagator matrix metho...

Anisotropic enhancement of group velocity in a homogenized dielectric composite medium

Under certain circumstances, the group velocity in a homogenized composite medium (HCM) can exceed the group velocity in its component material phases. We explore this phenomenon for a uniaxial dielectric HCM comprising isotropic component material phases distributed as oriented spheroidal particles. The theoretical approach is based upon the Bruggeman homogenization formalism. Enhancement in g...

Effective medium theory for anisotropic metamaterials

Materials with anisotropic material parameters can be utilized to fabricate many fascinating devices, such as hyperlenses, metasolids, and one-way waveguides. In this study, we analyze the effects of geometric anisotropy on a two-dimensional metamaterial composed of a rectangular array of elliptic cylinders and derive an effective medium theory for such a metamaterial. We find that it is possib...

Crack Models for a Transversely Anisotropic Medium

A commonly used model for a transversely anisotropic crack rock is that by Hudson (1980, 1981). This model is based on a simplified analysis of a thin circular crack, with displacement and stress conditions specified on the boundary. These papers have a second order correction in addition to the first order term in porosity/crack density. In this paper we compare the results of Hudson with thos...
