The dielectric relaxation of thick (∼50 μm) films of WO3 was investigated from 10 Hz to 1.8 GHz at a temperature of 200 °C. Three separate measurement techniques were employed: time-domain discharge voltage measurement, frequency-domain impedance measurement, and frequency-domain reflection coefficient measurement, with overlapping frequency ranges. Four distinct regions of dispersion were observed: below 100 Hz, the permittivity and loss tangent rise, implying a relaxation process; between 25 kHz and 1 MHz a second region of dispersion is observed with a loss peak at 80 kHz; from 1 to 300 MHz the dielectric response obeys the w-m power law of the Jonscher universal response with m=0.11; and above 500 MHz, another region of Debye-like loss is observed. © 2002 American Institute of Physics.
