- n. Any substance or medium that transmits the electric force by a process different from conduction, as in the phenomena of induction; a nonconductor, separating a body electrified by induction, from the electrifying body.
from The Century Dictionary and Cyclopedia
- Transmitting electric effects without conduction; nonconducting.
- n. A substance through or across which electric force is acting.

The Plasmocom team took a novel approach, developing what they called dielectric-loaded surface plasmon polariton waveguides (DLSPPW).
The team plans to mimic the longitudinal muscles with soft silicone rubber interspersed with a type of electroactive polymer EAP called a dielectric elastomer.
Ultimately the huge electrical stress exceeds the dielectric strength of the plastic, causing it to suddenly become conductive in a process called dielectric breakdown.
This phenomenon is called dielectric polarisation (Fig. 6.4.).
When the electrical field acts on a non-conductor (also known as dielectric), the not freely movable electrons can be displaced only insignificantly in the direction of the positive charge.
To be more accurate the specific inductive capacity of a dielectric is the ratio between the capacity of a condenser having that substance as a dielectric, to the capacity of the same condenser using dry air at zero degrees Centigrade and at a pressure of 14.7 pounds per square inch as the dielectric.
A dielectric is a material that does not conduct electricity.
A dielectric is a non-conducting substance, for example, an insulator: permittivity is a physical quantity that describes how an electric field affects, and is affected by a dielectric medium.
A floating gate is a component of the transistor that is fully enclosed by a thin insulating material called a gate dielectric, which isolates it electrically and allows it to retain its charge for years (in silicon devices).
The conceptual design and development of the sensor platform, called a dielectric slit die, was carried out at The National Institute of Standards and Technology (NIST) by the same principal scientists now directing R&D at T Bur Associates.
