Using this approach, data on the complex permittivity of sphalerite, magnetite, and labradorite in a 10--40 GHz frequency range have been obtained for the first time. A method is proposed for calculating the complex permittivity from experimentally measured frequency dependences of the reflection and transmission coefficients of a plane-parallel plate of a given mineral. Approximate expressions that can be used for calculations of the complex refractive index and permittivity of minerals are presented.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1406), last updated on Fri, 14 May 2021 23:32:08 -0500", issn="1063-7850", doi="10.1134/S1063785008110205", opturl="http://link.springer.com/10.1134/S1063785008110205", opturl="https://doi.org/10.1134/S1063785008110205" }
