Cavity resonator with tunable resonance frequency has cross-sectional plane that divides cavity into portions which are shiftable along common longitudinal axis

摘要

The cavity resonator has a round cross-section with alterable gap on the front portions of its cylindrical area. A cross-sectional plane (5) divides the cavity into sections (1,2) movable with respect to each other in the direction of a shiftable common longitudinal axis (z).
