Effect of Fiber Content and Temperature on the Dielectric Properties of Kenaf Fiber-filled Rigid Polyurethane Foam

open access: yesBioResources, 2014
Kenaf fiber-filled polyurethane foams were prepared using the free rising method. The dielectric constants and the loss tangents of the composites were studied as functions of fiber content (0, 5, 10, and 15 parts per hundred of polyols by weight ...

Effects of polymorphic form and particle size of SiO2 fillers on the properties of SiO2–PEEK composites

open access: yesJournal of Advanced Dielectrics, 2021
The effects of polymorphic form and particle size of SiO2 fillers on the dielectric, mechanical and thermal properties of SiO2–Polyetheretherketone (SiO2–PEEK) composites were investigated in this paper. Strong low frequency (

Dielectric-induced surface wave radiation loss [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
We investigate a model which shows how the introduction of a perturbing dielectric close to an electromagnetic surface wave leads to radiation away from the surface through the dielectric. This resembles a surface waveguide passing through a wall or being deployed underground.

Dielectric Behavior of α-Ag2WO4 and its Huge Dielectric Loss Tangent [PDF]

open access: yesMaterials Research, 2019
The microwave-assisted hydrothermal method was used to obtain α-Ag2WO4. Rietveld refinement confirmed that α-Ag2WO4 is stable in the orthorhombic phase, without secondary phase.
