Novel probe design for near field microwave and millimeter wave nondestructive testing techniques

Based on the numerical modeling the novel probe design for near field measurements is presented. The optimal electrodynamic characteristics of this probe with the dielectric insertion as melting quartz have been determined. It has been shown that the use of Teflon layer provides a good matching of wave impedances of the empty standard waveguide and reduced one. The testing probe instrument functions have been determined and expected values of resolving capacity are evaluated.
