Determination of Effective Permittivity and Permeability of Metamaterials from Reflection and Transmission Coefficients [PDF]
, 2002 We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lenghts of electromagnetic metamaterials, to determine the effective permittivity and permeability.

On the permittivity of titanium dioxide [PDF]
Scientific Reports, 2021 AbstractConductive rutile TiO2 has received considerable attention recently due to multiple applications. However, the permittivity in conductive, reduced or doped TiO2 appears to cause controversy with reported values in the range 100–10,000. In this work, we propose a method for measurements of the permittivity in conductive, n-type TiO2 that ...

Effective Permittivity of a Statistically Inhomogeneous Medium with Strong Permittivity Fluctuations [PDF]
Progress In Electromagnetics Research, 2004 Most previous multiple-scattering theories for electromagnetic waves in strongly fluctuating media are limited by the assumption of statistical homogeneity of media. In the paper, a lossy electrically isotropic random medium is considered whose mean permittivity distribution, as well as the multipoint permittivity's moments are invariant under ...

L‐band depolarised radar back scattering from Martian topographic surface: A numerical study
IET Radar, Sonar & Navigation, 2021 The interaction of radar signals with a planetary surface is critical for the utility of radar data. Herein, a power‐law roughness spectrum is used to model the roughness and an inhomogeneous vertical permittivity to describe the dielectrics from the ...
