Outline of Final Research Achievements	A linear relationship was obtained between amplitude attenuation and phase shift regardless of amount or density of silage filled into the waveguide around frequency 2GHz of microwave measured with the vector network analyzer. The gradient of attenuation and phase has increased as moisture content of raw silage rises. Possibility of non-destructive moisture measurement in silage was suggested by the relationship between attenuation and phase of transmitted microwave.
