| Abstract: | The Karp type slow wave structure loaded with dielectric is described in theory, and a general dispersion equation is obtained.The effect of the dimensions of Karp structure and the effect of the permittivity of the loaded dielectric on dispersion characteristics are calculated by computer. The results thus obtained show the significance of Karp structure as a slow wave type moisture content sensor.As is proved by theory and experiment, this type of microwave sensor has special advantages and will come into use in the microwave measurement technique of nonelectric quantities. |
