In view of the possible deformations of ridge waveguide devices in production

assembly and use

this paper studies the effects of displacement distortion and distortion under stress on the attenuation characteristics

power-handing capability and impedance characteristics of rectangular single ridge waveguides by using the finite element method.Numerical analysis results indicate that with the increase of deformations

the attenuation constant increases and the power-handing capacity and impedance decrease.But lateral deformation affects the characteristic parameters the most

so it should avoided as much as possible in the use of waveguide devices.
