NATURAL ELECTROMAGNETIC MODES IN CYLINDRICAL WAVEGUIDE JUNCTIONS AND THEIR USE FOR NONDESTRUCTIVE MICROWAVE MEASUREMENTS OF ELECTROMAGNETIC CHARACTERISTICS OF MATERIALS

摘要

On the basis of mathematical analysis of electromagnetic- modes in cylindrical and radial waveguide junction an automatic nondestructive complex allowing to measure electromagnetic parameters of materials (ferrites, leuoosapphires, etc.) was; developed. Complex is characterised 'by high sensitivity to variations of parameters and small error of measurements, confirmed by comparison of received data with ones of certified materials.
