Abstract :
Radiation from an axial magnetic-current element in the presence of a corrugated cylinder is considered. It is indicated that the power radiated in a given mode depends on the surface reactance, the circumference of the cylinder and the elevation angle. For certain values of the parameters, particular modes are strongly excited in a manner corresponding to the resonance condition of the circumferential (or spiral) surface waves.
