Definition of dielectric in English:
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.

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.

- 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.
