Due to its advantages of high power capacity , weak dispersion , easier fabrication and low ohmic losses , the folded rectangular groove guide would be an excellent slow - wave structure in millimeter and submillimeter wave twts 曲折矩形槽波導(dǎo)結(jié)合了曲折波導(dǎo)散熱能力強(qiáng)、色散特性好、容易加工和矩形槽波導(dǎo)單模工作、低損耗、大尺寸等優(yōu)點,因此這種新型的慢波系統(tǒng)有可能在毫米波及亞毫米波段的行波管中具有較好的發(fā)展前景。
