Waveguides, one of the most effective ways to carry electromagnetic energy, have application areas such as microwave communication systems, internet networks, radars, space exploration, optics and aviation. Sudden changes in the size or shape of the waveguides, such as bends and twists, can cause reflections and overall loss of efficiency. When such a change is required, the bends and twists of the waveguides must provide certain conditions to prevent reflections. This paper describes a new method to evaluate the attenuation constant for a circular dielectric or metallic waveguide having uniform curvature. When the radius of curvature “Ro” is large compared to the radius “a” of the waveguide field components can be obtained directly using toroidal coordinate system for the curved section of the waveguide instead of obtaining from those obtained for straight waveguide using perturbation techniques. Results obtained show excellent agreement with those given in the literature.
