The power capacity

attenuation constant and characteristic impedance of ridge waveguides are the major parts of their transmission characteristics.In their daily applications

their components are sure to subject to certain deformations.This paper calculates the impacts of displacement and stress deformation of triangular ridge waveguides on their power capacity

attenuation constants and characteristic impedance by applying ANSYS modeling in combination with MATLAB software.The results indicate that displacement deformation brings about relative minor effect on the attenuation constant

while bottom deformation produces relatively major effects on various characteristic parameters.These study results can provide some reference for the extensive applications of triangular ridge waveguides.
