Abstract The dielectric properties of shelled,
yellow-dent field corn were measured at frequencies of 1, 5, 20, 50, 100, and
300 MHz and 1, 2.45, and 11 GHz for moisture contents ranging from 10% to 40%
moisture, wet basis. Resulting dielectric properties are presented
graphically to illustrate the dependence of the dielectric constant and the
dielectric loss factor on frequency and moisture content. Coefficients of
variation are presented for repeated measurements and for the variation in
the dielectric properties among different lots of corn. The dielectric
constant is the most reliable dielectric property to use for moisture content
determination by dielectric measurement methods. |
