Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we propose a specific structure for nonreciprocal composite right/left hand transmission line consisting of ferrite-slab-loaded waveguide. By configuring nonreciprocal transmission-line resonator with reflectors at both terminals, this structure achieves high radiation efficiency and enables beam scanning through changes in the applied DC magnetic field.
