Full-wave electromagnetic modes and hybridization in nanoparticle dimers [PDF]

, 2019
The plasmon hybridization theory is based on a quasi-electrostatic approximation of the Maxwell’s equations. It does not take into account magnetic interactions, retardation effects, and radiation losses. Magnetic interactions play a dominant role in the

Complex Permittivity Measurement System for Solid Materials Using Complementary Frequency Selective Surfaces

IEEE Access, 2020
This paper describes a novel method of characterizing complex permittivity using a complementary frequency selective surface (CFSS). The CFSS provides a passband behavior and the change in the passband when a material under test (MUT) is placed adjacent ...

Electromagnetic Absorbers based on High-Impedance Surfaces: From ultra-narrowband to ultra-wideband absorption

Advanced Electromagnetics, 2012
Different electrically-thin absorbing designs based on  High-Impedance Surfaces (HIS) are presented and classified on the basis of the nature of loss. HIS structures allow achieving absorption by exploiting either dielectric or ohmic (resistive) losses ...

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a

High-Q trenched aluminum coplanar resonators with an ultrasonic edge microcutting for superconducting quantum devices

Scientific Reports, 2023
Dielectric losses are one of the key factors limiting the coherence of superconducting qubits. The impact of materials and fabrication steps on dielectric losses can be evaluated using coplanar waveguide (CPW) microwave resonators.

Curvature-induced radiation of surface plasmon polaritons propagating around bends [PDF]

, 2007
We present a theoretical study of the curvature-induced radiation of surface plasmon polaritons (SPPs) propagating around bends at metal-dielectric interfaces. We explain qualitatively how the curvature leads to distortion of the phase front, causing the

Static dielectric constant and dielectric loss of cellulose insulation: Molecular dynamics simulations

High Voltage, 2021
Reducing the dielectric constant and loss of cellulose insulation can make the electric field distribution uniform in oil‐paper insulation systems and decrease the heat generation in dielectric materials, thus ensuring a reliable transformer operation ...

Magnetic field tuning of polaron losses in Fe doped BaTiO3 single crystals

, 2012
Artificial tuning of dielectric parameters can result from interface conductivity in polycrystalline materials. In ferroelectric single crystals, it was already shown that ferroelectric domain walls can be the source of such artificial coupling.

CaZn1/3Nb2/3O3-based dielectric ceramics for silver co-sintering applications [PDF]

Science of Sintering, 2012
The Ca(Zn1/3Nb2/3)O3 (CZN) complex perovskite oxide has been studied for its attractive dielectric properties (εr=34, Qxf=15 890GHz, τf=-48 ppm.°C-1) for applications such as multilayer ceramics capacitors or hyperfrequency resonators.
