Abstract

A moisture measuring technique is presented which is based on the "free-space" measurement of the complex permittivity of the material in the microwave and millimeter-wave frequency range. This method is fast, accurate, nondestructive, and contactless. Moreover, operation at these frequencies enables one to measure a wide range of moisture content accurately with high resolution and at high temperatures.
