Distortion of electric field homogeneity between two thin toroidal electrodes by a dielectric sphere [PDF]

Serbian Journal of Electrical Engineering, 2022
We assess the influence of a radius and a relative permittivity of an isotropic dielectric sphere on electric field homogeneity. The homogenous electric field is generated using two thin toroidal electrodes, charged by equal charges of opposite ...

Cloaking and Magnifying Using Radial Anisotropy [PDF]

Journal of Applied Physics 114, 044110 (2013), 2013
This paper studies the electrostatic responses of a polarly radially anisotropic cylinder and a spherically radially anisotropic sphere. For both geometries, the permittivity components differ from each other in the radial and tangential directions.

The dielectric calibration of capacitance probes for soil hydrology using an oscillation frequency response model [PDF]

Hydrology and Earth System Sciences, 1998
Capacitance probes are a fast, safe and relatively inexpensive means of measuring the relative permittivity of soils, which can then be used to estimate soil water content.

The Effect of Interfacial Zone Due to Nanoparticle–Surfactant Interaction on Dielectric Properties of Vegetable Oil Based Nanofluids

IEEE Access, 2021
Nanoparticles are generally anti-lipophilic and have a tendency to aggregate when they are embedded in nanofluids. Thus, surfactants have a major role in achieving long term dispersion stability of nanofluids through surface modification of nanoparticles.

Modeling columnar thin films as platforms for surface-plasmonic-polaritonic optical sensing

, 2009
Via exploitation of surface plasmon polaritons (SPPs), columnar thin films (CTFs) are attractive potential platforms for optical sensing as their relative permittivity dyadic and porosity can be tailored to order. Nanoscale model parameters of a CTF were
