| 20100001747 | METHOD AND A DEVICE FOR MEASURING DIELECTRIC CHARACTERISTICS OF MATERIAL BODIES - The inventive method for measuring dielectric characteristics of material bodies consists in generating a microwave signal, in dividing said signal into reference and sounding signals, in irradiating a body with the microwave signal when a waveguide probe contacts a tested material, in receiving the reflected, reference and total signals and in detecting said signals. The irradiation is carried out by means of a waveguide wave, the propagation number of which in the free space of the waveguide probe, which is filled with a prism-shaped dielectric insert,—“[εk | 01-07-2010 |
