Definition Of dielectric
a medium or substance that transmits electric force without conduction; an insulator.
In many photonic structures composed of two or more dielectrics , the absolute value of the refractive index contrast is critical to performance.
having the property of transmitting electric force without conduction; insulating.
The accumulation of excessive electric charge in dielectric insulation is extremely rare, but when it does occur, it is often catastrophic.
Example Of dielectric
According to another embodiment, the second cover is dielectrically isolated from a current collector.
An electrically polarizable object will be trapped in a region of a focused electric field, provided there is sufficient dielectric response to overcome thermal energy and the electrophoretic force.
At that size, it expects to make use of new materials and high-k dielectrics .
But low-k dielectrics improve the insulation between the circuits, thus allowing efficient transistor switching without the need for excessive power, and consequently without the extra heat.
In addition, for systems composed of dielectrically significantly dissimilar regions, ionic energetics is sensitive to the long-range artifacts imposed by periodic boundary conditions.
