Abstract

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 2f_c, and converts the TE₁₀ mode into the TE₄₀ mode for frequencies higher than 2f_c, which is achieved by a combination of TE₁₀-TE20 mode converters.
