Abstract :
A waveguide is described that propagates at two frequency bands with low loss and good bandwidth. The structure is achieved by the simple insertion of a frequency selective surface (FSS) to form a guide within a guide. The transmission response is tailored by the response of the FSS. The technique lends itself to other waveguide geometries, and many combinations of frequencies can be accommodated.<>
