Low-frequency dielectric measurements (10^-4to 6 × 10⁴Hz): a new computer-controlled method

Abstract

An apparatus is described which allows examination of the dielectric response of a sample over a frequency range of 10-4 to 6 × 104 Hz. The apparatus is capable of measuring loss tangents down to 10-4 for samples with capacitances of a picofarad and upwards.
