| Abstract: | Moisture is a significant parameter of coal quality.Traditional methods for moisture determination are complex and time-consuming.Via analyzing the impact of the permittivity of media filled in a rectangular waveguide upon the cutoff frequency,a technique of determining the moisture of coal is raised,and the proposed method possesses the advantages of fast detection,high resolution,non-touching and high tolerance to the interferences. |

| Keywords: | moisture microwave cutoff frequency |
