Abstract
A concept of moisture content determination from the measurement of th e attenuation and phase shift of an electromagnetic wave transmitted t hrough a layer of wet material is explored in the paper. Experimental results for wheat of 10 to 19% moisture content (wet basis) at tempera tures from -1 degrees; to 42 degrees C at the frequency of 16.8 GHz ar e used to illustrate the procedure which provides a density-independen t and temperature-compensated moisture content determination.
