Determination of the Permittivity of Transmission Lines at Milli-Kelvin Temperatures
IEEE Access, 2023 Many quantum technologies rely heavily on propagation of RF and microwave signals through devices at cryogenic temperatures, and detailed understanding of materials and signal propagation is therefore key to improving the performance of quantum circuits.

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,

Relative Permittivity of Stockmayer-Type Model Fluids from MD Simulations and COFFEE
, 2022 The relative permittivity is a property that depends on the orientation structure of a fluid. Thus, using state-of-the-art equations of state it can be modeled only when using high level techniques, such as nonprimitive models.

Measurement of the effective relative permittivities of microstrip
Electronics Letters, 1975 A new method for determining the effective relative permittivity of microstrip, even at high frequencies, is presented. Four microstrips having the same physical and geometric characteristics, but different lengths, are needed; the mismatch due to the launchers is completely overcome.

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 ...
