Abstract :
A perturbation analysis is employed to obtain a modal equation for diffraction by a perfectly conducting cylindrical surface with a sinusoidal perturbation of the height profile. It is found that the surface impedance concept has a measure of validity in describing the fields averaged over one period of the surface.
