All-dielectric invisibility cloaks made of BaTiO3-loaded polyurethane foam [PDF]

open access: yes, 2011
Transformation optics has led the way in the development of electromagnetic invisibility cloaks from science fiction to engineering practice. Invisibility cloaks have been demonstrated over a wide range of the electromagnetic spectrum, and with a variety

Effect of microwave vacuum puffing conditions on the dielectric properties of berries

open access: yesScientific Reports
The objective of this study was to study the effect of microwave vacuum puffing (MVP) conditions on dielectric properties of berries. A central composite response surface experiment, with four factors and five levels, was carried out to assess the effect

Dielectric properties of multi-phase carbon nanofiber/polyethylene composites

open access: yesJournal of Aeronautical Materials, 2020
An attractive type of nanofiller-carbon nanofiber (CNF) was used to modify High-density Polyethylene (HDPE) and polymer blends (UH-HDPE) of HDPE and ultra-high molecular weight polyethylene (UHMWPE), and two-phase and three-phase nanocomposites were ...

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 ...
