Determination of an efficient power equipment oil through a multi-criteria decision making analysis [PDF]

open access: yesVojnotehnički Glasnik, 2022
Introduction/purpose: Several studies in the area of the development of nanofluids for power equipment have left a gap unfilled as to how to determine the best oil among the produced oils for power equipment application. Therefore, this study presents

Ferromagnetic/ferroelectric composites and microwave properties of its metamaterial structure

open access: yesCailiao gongcheng, 2020
A series of YIG/BST ferromagnetic/ferroelectric composites were prepared by solid-state reaction using yttrium iron garnet (Y3Fe5O12) and barium titanate (Ba0.5Sr0.5TiO3).

Influences of graphene nanoplatelet aspect ratio and thermal treatment on dielectric performances of poly(methyl methacrylate) composites

open access: yesHigh Voltage, 2016
The dielectric property and percolated behaviour of polymer matrix composites largely depend on the morphology of conductive fillers and external stimulations especially when the composites are processed by melting blending and extrusion-injection way ...

Thermal conductivity and dielectric properties of bismaleimide/cyanate ester copolymer

open access: yesHigh Voltage, 2017
The blend was synthesised with bismaleimide (BMI) resin and bisphenol A-based cyanate ester (BADCy) resin. The BMI/BADCy copolymer showed excellent dielectric and thermal conductivity properties. The volume resistivity of the copolymer was a little lower

Dielectric spectroscopy of Tobacco Mosaic Virus [PDF]

open access: yes, 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.

Effects of electric quadrupole interactions with tunable atomic mirrors

open access: yesAlexandria Engineering Journal, 2023
Recent studies have involved electric quadrupole effects in atoms interacting with the evanescent mode. This type of surface mode is usually produced by the total internal reflection in a dielectric-vacuum atz=0, and its intensity distribution is very ...

Image charge inclusion in the dielectric sphere revisited [PDF]

open access: yes, 2012
Van Siclen (1988 Am. J. Phys. 56 1142) reported a curious property of a dielectric sphere in the field of an external point charge: the field outside the sphere generated by the combination of the original charge exterior and the Kelvin image charge ...

Diffraction by an acoustically penetrable or an electromagnetically dielectric half plane II [PDF]

open access: yes, 1989
The present work gives a mathematical model for an acoustically penetrable or electromagnetically dielectric half plane. An approximate boundary condition is derived which depends on the thickness of, and the material constants which constitutes, the ...
