SUMMARY OF Phase-nonreciprocal metamaterials support wave propagation with positive and
Ph.D THESIS: negative refractive indices in opposite directions at the same frequency. This
phenomenon was applied to the design of pseudo-traveling-wave resonator and
leaky wave antenna with enhanced gain, directivity and beam scanning at a fixed
frequency. The general problem of conventional leaky wave antennas is beam
squinting. Beam squinting is reduced in pseudo-traveling-wave resonance-type
antennas. In this work, it was comprehensively demonstrated that beam squinting
can be eliminated when nonreciprocity in phase constant have a non-dispersive
frequency profile. The discussed metamaterial design can also be applied to new
beam antenna with polarization rotation switching by the means of dc magnetic field.
The problem of microstrip line-based nonreciprocal metamaterials is insufficient
magnitude of nonreciprocity. An approach to enhancing the nonreciprocity in phase
constant alone was proposed using a ferrite loaded coplanar waveguide structure.
The advantage of the approach is in using the same materials as in previous work,
while allowing operation on higher frequencies with higher magnitude of
nonreciprocity.
