Dielectric complex reluctance — is a scalar measurement of a passive dielectric circuit (or element within that circuit) dependent on sinusoidal voltage and sinusoidal electric induction flux, and this is determined by deriving the ratio of their complex effective amplitudes.… … Wikipedia
Dielectric — A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their … Wikipedia

capacitance — /keuh pas i teuhns/, n. Elect. 1. the ratio of an impressed charge on a conductor to the corresponding change in potential. 2. the ratio of the charge on either conductor of a capacitor to the potential difference between the conductors. 3. the… … Universalium
Radio frequency heating — is the heating of materials by radio frequency (otherwise called electromagnetic) energy. This can be divided into 3 general categories as below. The term radio frequency is misleading electromagnetic energy of any frequency is absorbed (and… … Wikipedia
Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… … Wikipedia
