Abstract (in Japanese) (See Japanese page) 
(in English) This paper studies on 4-port circulators comprising of coupled nonreciprocal composite right/left handed (CRLH) metamaterial lines. The dispersion diagrams for the CRLH lines elucidate the fundamental characteristics of the nonreciprocal transmission/reflection. Our numerical calculations shows that the coupled line comprising of the CRLH metamaterial works as a 4 port circulator.
