Free Space Dielectric Techniques for Diamond Composite Characterization

IEEE Journal of Microwaves
Compact millimeter-wave arrays demand novel packaging solutions that feature low-cost dielectric materials with significant thermal conductivity ($\sim$100 W/m ⋅ K). To characterize the permittivity and loss tangent of the dielectric

Proposal of a generic constitutive model for deformation-dependent dielectric constant of dielectric elastomers

Engineering Science and Technology, an International Journal, 2021
Dielectric elastomers (DEs) are electroactive polymers that could be used as soft actuators, stretchable generators and sensors. Their performance is dependent on both their mechanical and dielectric properties.

Structural and Dielectric Characterization of Sm2MgMnO6 [PDF]

Journal of Nano- and Electronic Physics, 2017
The polycrystalline Sm2MgMnO6 (SMMO) was synthesized at 1173K by means of sol-gel technique. Rietveld refine-ment of X-ray diffraction (XRD) pattern confirmed the formation of a single phase monoclinic structure with space group P21/n. The band gap achieved from UV-vis spectra shows the semiconducting nature of the material.

Dielectric Characterization of a Nonlinear Optical Material [PDF]

Scientific Reports, 2014
Batisite was reported to be a nonlinear optical material showing second harmonic generation. Using dielectric spectroscopy and polarization measurements, we provide a thorough investigation of the dielectric and charge-transport properties of this material. Batisite shows the typical characteristics of a linear lossy dielectric.
