Dielectric permittivity of dusty plasma in the Earth's mesosphere

open access: yesEarth and Planetary Physics, 2021
This paper deals with the dielectric permittivity of dusty plasma in the earth’s mesosphere. We give expressions for the complex dielectric permittivity of dusty plasma, taking into account the effects of the dust charging process and magnetic field.

Dielectric permittivity of C-S-H

open access: yesCement and Concrete Research, 2022
As a porous hydrophilic phase, C–S–H is expected to exhibit a frequency-dependent dielectric response. This C–S–H property remains unknown, despite the importance of dielectric assessment for non-destructive evaluation of concrete. This study adopts a multiscale approach to estimate the complex dielectric response of C–S–H over the 0 to 1000 GHz ...
