Properties of Metal/Dielectric/Metal and Dielectric/Metal/Dielectric Nanowaveguide Structures

2018 International Conference on Information and Telecommunication Technologies and Radio Electronics (UkrMiCo), 2018
In this paper we present the results of the analysis of symmetric nanowaveguides of two types: dielectric/metal/dielectric and metal/dielectric/metal. In the analysis, the following metals were used: gold, silver and aluminum. Calculations have shown that from the point of view of minimizing the thickness of the waveguide and the minimum absorption ...

The dielectric circuit

Electrical Engineering, 1937
The dielectric circuit is a baffling enigma to many undergraduate students of electrical engineering; indeed, to many engineers whose work is not intimately concerned with it. This outline of some of the elementary notions regarding electrostatics and the dielectric circuit is presented here because of its possible interest and value to students and ...

Dielectric-metal-dielectric nanotip for SNOM

SPIE Proceedings, 2009
Superfocusing of light, far better than the diffraction limit, is of crucial importance for scanning near-field optical microscopy (SNOM), optical chemical sensing, and nanolithography. For SNOM applications there are two typical geometries. The first are tapered-fiber metal-coated aperture probes, which are being constantly improved.

ON GENERALIZED THERMOELASTIC DIELECTRICS

Journal of Thermal Stresses, 1981
A complete nonlinear constitutive theory of thermoelastic dielectrics including polarization effects is derived by using a modified entropy production inequality proposed by Green and Laws [1] and independently by Suhubi [2].∗ The constitutive equations of thermorigid dielectrics are also obtained.

Dielectric Relaxation in Disordered Polar Dielectrics

Ferroelectrics, 2002
A review of the current understanding of the effect of crystal lattice defects on the low-frequency dielectric relaxation properties in single crystals and polycrystalline polar dielectrics is given. Special attention is paid to different long-term phenomena, found in dielectric experiments, such as a low frequency relaxation polarization, a very slow ...

Dielectric relaxation in distributed dielectric layers

Journal of Applied Physics, 1984
The Maxwell–Wagner theory of interfacial polarization was extended to the layer system in which the layer properties are distributed continuously. The equation was derived to transform the distribution of relaxation times into that of layer properties. Each layer was characterized by the thickness and by the time constant which is defined as the ratio ...

Dielectric relaxation and dielectric mixtures: similarities

CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005
Spectral density representation is a tool to analyze electrical properties of material mixtures and the geometrical description of the system. The aim of this paper is to derive an expression for the spectral density representation, which favors dielectric relaxation phenomenon.

On the dispersion of the dielectric constant of an inhomogeneous dielectric

Soviet Physics Journal, 1969
The influence of an inhomogeneity, smoothly distributed through the thickness of a sample, on the dielectric properties of the sample is discussed. An estimate is made of the degree of inhomogeneity in a dielectric film on a base of manganese oxide.
