Microwave dielectric properties of ceramics: A clue to its intrinsic dielectric response

open access: yesJournal of Advanced Dielectrics, 2023
CaCu3Ti4[Formula: see text] (CCTO) is a potential dielectric material with giant permittivity, good stability over the wide temperature and frequency range. However, the dielectric responses of CCTO-based ceramics are mainly investigated in the frequency

Colossal permittivity and ultralow dielectric loss in Nb-doped SrTiO3 ceramics

open access: yesJournal of Advanced Ceramics, 2023
Defect engineering has been applied to prepare materials with modifiable dielectric properties. SrTiNbxO3 (x = 0, 0.003, 0.006, 0.009, 0.012) ceramics were synthesized using the traditional solid-state reaction method and sintered in a reducing ...

Determination of Dielectric Losses in a Power Transformer

open access: yesEnergies, 2022
The article presents a method of determining dielectric losses that occur in insulating materials in a power transformer. These losses depend mainly on the electric field stress, pulsation, dielectric loss coefficient, and electrical permittivity of ...

Magnetoquasistatic resonances of small dielectric objects [PDF]

open access: yes, 2019
A small dielectric object with positive permittivity may resonate when the free-space wavelength is large in comparison with the object dimensions if the permittivity is sufficiently high.
