ROUND WAVEGUIDE WITH LAMINATE FILLING

摘要

FIELD: radio engineering. SUBSTANCE: invention is related to waveguide equipment, specifically to lines for transmission of electromagnetic oscillations and may find use in microminiaturization of waveguide sections. Invention is directed to solution of problem coupled to increase of critical length of wave with expansion of working range of waveguide. Mentioned task is achieved thanks to usage of different electric parameters of media filling central and peripheral parts of waveguide and thanks to required geometry of structure. EFFECT: expanded working range of waveguide.
