Dielectric loss
= Dielectric loss
{wiki}
Conversion of electrical <energy> into heat in a <dielectric> driven by an <electric field>. In the stated harmonic convention, a passive scalar response has $\epsilon''\geq0$ for positive <angular frequency>. A <dielectric capacitance measurement> measures a dissipative component as well as <capacitance>; leakage from <electrical conductivity> can contribute to the inferred loss.
