Graphs of resistivity and dielectric constant vs. temperature are difficult to translate to values of electronic components. The electronic design engineer is more concerned with how much a resistor changes with temperature and if the change drives the circuit parameters out of specification. The following defines the commonly used terms for components related to temperature variation.

Most work to date has concentrated on a particular aspect of microwave properties, e.g. conductivity or dielectric constant, with few studies of the complete spectrum of properties over broad frequency ranges. For example. Fig. 12-2a.b show the DC vs. microwave (6.5 GHz) conductivity and the microwave (6.5 GHz) dielectric constant vs. temperature for a series of poly(anilines) measured by Javadi et al. [195]. The behavior observed- microwave conductivity greatly exceeding DC conductivity for higher doping levels, and dielectric constant being independent of temperature for low doping levels- is typical of CPs. Buckley and Eashoo [430] obtained relatively poor values for e and e", ca. 90 and 60 (at the Ka band, ca. 33 GHz) for compacted P(Py)/Cl powder.
