Abstract

In this project we study the behavior of the permittivity and loss tangent of a class of materials that exhibit relaxation. For relaxation response we show that the permittivity is a monotonically decreasing function of frequency. Also, for many low-liss ceramics, glasses, crystals, and solid polymers it is found that the loss tangent increases nearly linearly with frequency. This linearity is explained in terms of the pulse-response function and the Sparks-King-Mills model. We show that the linearity may be used to extrapolate the loss tangent out of the measurement band
