On the permittivity of titanium dioxide [PDF]

open access: yesScientific 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 ...

Processing Radargrams to Obtain Resistivity Sections

open access: yesRemote Sensing, 2022
Ground penetrating radar (GPR) is routinely used to locate the isolated elements that produce reflection hyperbolas in radargrams. However, we propose a method in this study for locating the various interfaces appearing in a medium by studying the signal

Effective Permittivity of a Statistically Inhomogeneous Medium with Strong Permittivity Fluctuations [PDF]

open access: yesProgress 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 ...
