Abstract

Abstract

This paper studies the dispersion characteristics and the Pierce interaction impedance of Ku-band folded-waveguide(FW) slow-wave structure(SWS) Shielded by Photonic crystals(PhC). The structure is simulated with the code CST MWS, and the selectivity of PhC to electromagnetic waves in the SWS is discussed. The results reveal that the dispersion of the FW SWS with PhC is smaller than that without PhC, while its Pierce interaction impedance is slightly higher.
