Dielectric constant and losses in a magnetic field in RexMn1-xS solid solutions (Re = Gd, Yb) [PDF]

E3S Web of Conferences
Polycrystalline samples GdxMn1-xS and YbxMn1-xS with a concentration x = 0.2, near the ions percolation concentration through the face-centered cubic lattice, are studied in order to determine fluctuations in the valence of the ytterbium ion on ...

Tailoring Dielectric Properties of Multilayer Composites Using Spark Plasma Sintering [PDF]

, 2007
A straightforward and simple way to produce well-densified ferroelectric ceramic composites with a full control of both architecture and properties using spark plasma sintering (SPS) is proposed. SPS main outcome is indeed to obtain high densification at

Dielectric spectroscopy of Tobacco Mosaic Virus [PDF]

, 2003
The dielectric properties of the Tobacco Mosaic Virus (TMV) have been measured using time domain dielectric spectroscopy (TDDS) in the temperature range from 1 to 40 jC. A single dielectric dispersion is observed in the MHz range.

Complex Permittivity Measurement System for Solid Materials Using Complementary Frequency Selective Surfaces

IEEE Access, 2020
This paper describes a novel method of characterizing complex permittivity using a complementary frequency selective surface (CFSS). The CFSS provides a passband behavior and the change in the passband when a material under test (MUT) is placed adjacent ...

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]

, 2006
A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...

Electromagnetic Absorbers based on High-Impedance Surfaces: From ultra-narrowband to ultra-wideband absorption

Advanced Electromagnetics, 2012
Different electrically-thin absorbing designs based on  High-Impedance Surfaces (HIS) are presented and classified on the basis of the nature of loss. HIS structures allow achieving absorption by exploiting either dielectric or ohmic (resistive) losses ...

High-Q trenched aluminum coplanar resonators with an ultrasonic edge microcutting for superconducting quantum devices

Scientific Reports, 2023
Dielectric losses are one of the key factors limiting the coherence of superconducting qubits. The impact of materials and fabrication steps on dielectric losses can be evaluated using coplanar waveguide (CPW) microwave resonators.
