Dielectric rod arrays in a metallic waveguide alter the propagation modes and group velocities of electromagnetic waves. We focus on TE10-to-TE20 mode converters and investigate the variation in their behavior with frequency. In this investigation, a mode converter is proposed that passes the TE10 mode at frequencies lower than 2fc, and converts the TE10 mode into the TE40 mode for frequencies higher than 2fc, which is achieved by a combination of TE10-TE20 mode converters.
