To reduce the intrinsic resistance-capacitance delay of back-end-of-line (BEOL) interconnects in integrated circuits, low-dielectric-constant (low- k ) materials with a dielectric constant ( k ) <4.0 have been introduced to be used as an interconnecting insulator from 130nm technological node. ...
The dielectric constant of air is very close to the dielectric constant of vacuum. This is why neither vacuum nor air increase the capacitance of a capacitor. On the other hand, solid dielectric substances such as polyethylene or glass, which have a higher dielectric constant, can sustain perman...
Dielectric permittivity is relatively high and remains constant during the dormant period, after that it decreases rapidly when the hydration reaction resumes and continues to decrease during the acceleratory period. 展开 关键词: Dielectric Permittivity Cementitious Materials Hydration Microwave Energy ...

The aim of this work is to check influence of high humidity ageing process on complex dielectric constant in polymeric material. This will help to determine water content in material which can be useful in diagnostic isolation of high voltage electrical equipment during service without need of disas...
