Light scattering by magnetoelectrically gyrotropic sphere with unit relative permittivity and relative permeability [PDF]
Journal of the Optical Society of America A, 2014 An exact transition matrix was formulated for electromagnetic scattering by a sphere made of a magnetoelectrically gyrotropic material with unit relative permittivity and relative permeability. The total scattering and forward scattering efficiencies are lower when the magnetoelectric gyrotropy vector of the sphere is either coparallel or antiparallel ...

Relative permittivity in the electrical double layer from nonlinear optics [PDF]
The Journal of Chemical Physics, 2018 Second harmonic generation (SHG) spectroscopy has been applied to probe the fused silica/water interface at pH 7 and the uncharged 11¯02 sapphire/water interface at pH 5.2 in contact with aqueous solutions of NaCl, NaBr, NaI, KCl, RbCl, and CsCl as low as several 10 μM. For ionic strengths up to about 0.1 mM, the SHG responses were observed to increase,

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 ...

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.
