On the permittivity of titanium dioxide [PDF]
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 ...

THE ANOMALOUS RISE OF CAPACITANCE OF C60 FULLERITE FILMS AT LOW FREQUENCIES: A CAUSE ANALYSIS
A known physical fact of the anomalous rise of dielectric permittivity ε of C60 fullerite films at ac low frequencies (below 1 kHz) has not had a convincing explanation up to now. Our study was aimed at elucidating the causes of that anomaly.

RESONANCE PROPERTIES OF AN X-BAND RECTANGULAR WAVEGUIDE SECTION WITH AN INHOMOGENEOUS DIELECTRIC INSET [PDF]
Subject and Purpose. In modern dielectrometry, the problem of detecting foreign inclusions in a radio-transparent material, which are significantly smaller than the operational wavelength, remains very important. The problem becomes even more complicated

Permittivity-Asymmetric Quasi-Bound States in the Continuum
Breaking the in-plane geometric symmetry of dielectric metasurfaces allows us to access a set of electromagnetic states termed symmetry-protected quasi-bound states in the continuum (qBICs).

Permittivity-asymmetric quasi-bound states in the continuum
Broken symmetries lie at the heart of nontrivial physical phenomena. Breaking the in-plane geometrical symmetry of optical systems allows to access a set of electromagnetic states termed symmetry-protected quasi-bound states in the continuum (qBICs ...
