Abstract
Dielectric rod arrays in a metallic waveguide alter the propagation modes and group velocities of electromagnetic waves. We focus on TE<sub>10</sub>-to-TE<sub>20</sub> mode converters and investigate the variation in their behavior with frequency. In this investigation, a mode converter is proposed that passes the TE<sub>10</sub> mode at frequencies lower than 2f<sub>c</sub>, and converts the TE<sub>10</sub> mode into the TE<sub>40</sub> mode for frequencies higher than 2f<sub>c</sub>, which is achieved by a combination of TE<sub>10</sub>-TE</sub>20 mode converters.
