Dielectric tensor for interfaces and individual layers in magnetic multilayer structures" (2000). The magneto-optical Kerr response of metallic magnetic multilayers has been studied by determining the dielectric tensors ͑dielectric functions͒ for individual layers, including the magnetic and nonmagnetic interfacial layers. The diagonal components of these tensors were determined using in situ ell...

Metal–dielectric multilayer metamaterials with extreme loss-anisotropy, in which the longitudinal component of the permittivity tensor has an ultra-large imaginary part, are proposed and designed. Diffraction-free deep subwavelength beam propagation and manipulation, due to the nearly flat iso-frequency contour, is demonstrated in such loss-anisotropic metamaterials. It is also shown that deep ...

In a Coulomb fluid confined to a domain V , the dielectric susceptibility tensor χV depends on the shape of V , even in the thermodynamic V → ∞ limit. This paper deals with the classical two-dimensional one-component plasma formulated in an elliptic V -domain, equilibrium statistical mechanics is used. For the dimensionless coupling constant Γ = even positive integer, the mapping of the plasma ...

Using the effective Lagrangian for the low energy photon-photon interaction the lowest order photon self energy at finite temperature and in nonequilibrium is calculated within the real time formalism. The Debye mass, the dispersion relation, the dielectric tensor, and the velocity of light following from the photon self energy are discussed. As an application we consider the interaction of pho...

For magneto-optical(MO) recording media we propose particulate films with magnetic fine particles dispersed in binders. Using effective dielectric tensor Faraday rotation ~ and absorption coefficient -a-are calculated for the particulate films containing Bi-substituted YIG and Co fine particles. The MO figure of merit O'~ of the particulate films exceeds that of continuous magnetic films. This ...

A system of three electrolytes separated by two parallel planes is considered. Each region is described by a dielectric constant and a Coulomb fluid in the Debye-Hückel regime. In their book Dispersion Forces, Mahanty and Ninham have given the van der Waals free energy of this system. We rederive this free energy by a different method, using linear response theory and the electrostatic Maxwell ...

A unified theoretical description of static and dynamic properties of ferroelectric l iquid crystals in terms of a Landau free energy is presented. The shear deformation tensor is used as principal order parameter. Results for the stationary case for t i l t angle variat ion and dielectric properties are compared with experiments on a compound wi th a pronounced first-order S m A S m C * phase ...

We employ a homogenization technique based on the Lorentz electronic theory to show that planar chiral structures (PCSs) can be described by an effective dielectric tensor similar to that of biaxial elliptically dichroic crystals. Such a crystal is shown to behave like a PCS insofar as it exhibits its characteristic optical properties, namely, corotating elliptical polarization eigenstates and ...
