Abstract :
A slow-wave structure based on a corrugated waveguide employing photonic crystal (PhC) lateral walls is proposed for THz vacuum devices. The PhC design alleviates typical issues arising in THz tubes assembly without affecting the interaction process. A backward-wave oscillator based on the proposed technology is designed and simulated using 3D particle-in-cell code, obtaining more than 90 mW-peak output power at 0.641 THz.
