A corrugated waveguide with Photonic Crystal (PhC) wall is proposed for effective beam-wave interaction with wide sheet beams at terahertz frequency. Compared to conventional corrugated waveguides, PhC technology provides efficient field confinement in a naturally open structure which allows for improved level of vacuum pumping alleviating the typical assembling issues.
