Study of Slow Wave Structure with Double Corrugated Waveguide Shielded by Photonic Crystals

Abstract

A Double Corrugated Waveguide Shielded by Photonic Crystal (PhC) wall is proposed for effective beam-wave interaction with a circular beam at terahertz frequency. Numerical results reveal that the The phase velocity and Pierce interaction impedance for Double Corrugated Waveguide Shielded by Photonic Crystals are higher in the frequency of Photonic band gap compared with conventional Double Corrugated Waveguide.
