dielectric
- n a material such as glass or porcelain with negligible electrical or thermal conductivity
- Radar's ability to report what it sees depends on differences in its targets' reflecting power (which engineers call the "dielectric constant").
- By the A P: an electronic food defroster, using dielectric heat, for quick thawing of frozen foods.
- The results were invariably the same: the bugs, consisting, as the scientists note, of an excellent dielectric (the exoskeleton) surrounding an electrolyte (the body fluids .
