Abstract
A method proposed previously [1], according to which high-order modes in a barrel-shaped cavity are selectively excited using a coaxial waveguide with a double periodic perforation of the wall, has been experimentally realized. A rotating H11 waveguide mode has been converted into a rotating H531 eigenmode with a conversion efficiency of about 98%.
