Abstract :
This paper newly proposes a microstrip line on the oppositely magnetized ferrite substrate. Strong nonreciprocal transmission characteristic was confirmed with both theory and experiments. After discussions of the physical meaning of nonreciprocity of the line, a nonreciprocal four port junction and new design of a ring circulator along singular point of the bias field were demonstrated as applications of the strip line proposed.
