摘要: A new type of printed rectangular helix slow-wave structure (SWS) is investigated using the field-matching method and electromagnetic integral equations at boundaries. The radio-frequency characteristics including dispersion equation coupling impedance for transverse antisymmetric (odd) modes this are analysed. numerical results agree well with obtained by EM simulation software HFSS. It shown that circuit weakened, phase velocity reduced after filling dielectric materials in SWS. As a planar structure, has potential applications compact TWTs.
