Abstract: 

A rigorous mathematical model of the diffraction of an electromagnetic wave in the bend of a plane-parallel waveguide is constructed. Within numerical simulation of the waveguide bend the effect of its complete locking at a frequency located nearby the critical frequency of the second mode is revealed. The resonant nature of this effect, which consists of excitation of locking oscillation in this waveguide inhomogeneity, is found. The conclusion is that the bend of a waveguide could be considered as an open-type waveguide resonator. The importance of the solved problem is caused by wide waveguide bends applications in the microwave technology.
Keywords: finite difference method, full reflection resonance, waveguide bend, waveguide corner bend
