Scanning near-field microwave microscope

We explored an experimental device of scanning near-field microwave microscope (SNFMM), where as probe used open end of coaxial waveguide. This piece of coaxial by help coaxial-waveguide transition was connected to panoramic measuring device of SWR and attenuation P2-65. Frequency characteristic of reverberation coefficient of such device bore resonance nature, broke down under minimums system, situated off /spl lambda//sub 0//2 one another, amount of which determines by waveguide piece length. Such a descriptions, as change of resonance frequency of minimum, value of the reverberation coefficient in minimum, width of resonance curve carry information about parameters of sounded matter such as dielectric penetrability, conductivity, presence of heterogeneities and their character. Used a piece of coaxial waveguide with section, providing single-mode a routine in select frequency range.
