| Outline of Final Research Achievements |
In this work, we first proposed circularly polarized radiation from pseudo-traveling wave resonance antennas based on nonreciprocal metamaterials, and demonstrated it with polarization rotation direction switched by the applied dc magnetic field in the experiment. Second, combination of curvature of lines and asymmetric insertion of inductive stubs has been proposed and demonstrated to enhance the nonreciprocity. Third, design techniques of dispersion-less nonreciprocity in the metamaterials have been established and demonstrated to reduce beam squint to be solved in beam scanning antennas.
