Abstract

The effect of representing dielectric properties in terms of the complex polarizability αc = α′ − iα″ is examined. Loss curves (ε″ and tan δε) are shifted towards higher frequencies, revealing the existence of new relaxations and allowing the clarifications of ones already known. We have calculated the shift ratios ω (at maximum α″ or tan δα)/ω (at maximum ε″ or tan δα) from the more conventional empirical equations representing the dielectric behavior. Some examples are given.
