Principles of universalization of microwave facilities for diagnostics of small-scale objects

The principles of universialization of microwave facilities for diagnostics of different objects in a wide operating frequency range with a required locality are substantiated. A basic principle is the application of an aperture resonator measuring converter and a modulation system of the automatic frequency control (AFC) of a driving microwave oscillator by the measuring converter. The measuring converter aperture having a coaxial structure forms a local microwave probe. Fundamental signals are extracted in the analog form via the AFC system and after ADC they are processed by the standard digital technology. The quantitative dependences are given which characterize a possibility of optimizing the locality and sensitivity of tools by choosing the geometry of the aperture assembly. These diagnostics might be applied for investigations of the physical properties of thin film, biological objects, metamaterials, elements of thin-film electronics etc. ©2016 by Begell House, Inc.
