Abstract :
This paper presents a method of calculation of cutoff wave numbers and natural mode field functions in waveguides of rectangular cross section with rounded corners. The method is based on a solution of boundary integral equations of the potential theory. A special parametrization of the contour bounding the waveguide cross section is proposed.
