dielectric

/ˌdʌɪɪˈlɛktrɪk

Physics

adjective

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....

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.
The conductance caused by dielectric breakdown of membranes is proportional to the amplitude and duration of the electric field.

noun

A medium or substance with a dielectric property; an insulator.In many photonic structures composed of two or more dielectrics, the absolute value of the refractive index contrast is critical to performance....

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.

Derivatives

dielectrically

adverb ...

In addition, for systems composed of dielectrically significantly dissimilar regions, ionic energetics is sensitive to the long-range artifacts imposed by periodic boundary conditions.
The magnitude of the first effect depends on the (dielectrically weighted) relative depth of groups A and B in the membrane.
It is a dielectrically isolated, high-speed, complementary bipolar IC process that uses a technology called deep trench on bonded wafer, and enables complete dielectric isolation.

Origin

Mid 19th century: from di-³ + electric, literally 'across which electricity is transmitted (without conduction)'.
