Ferrite-ferroelectric nonlinear microwave phase shifter

چکیده
A nonlinear microwave phase shifter based on ferrite-ferroelectric composite material has been studied for the first time. The ferrite-ferroelectric composite is fabricated in the form of bilayer consisted of yttrium iron garnet and barium strontium titanate. A principle of operation of the device is based on the linear and nonlinear control of the phase shift of the hybrid spinelectromagnetic waves propagating in the bilayer. The device demonstrated a dual-function performance with a nonlinear phase shift up to 140 degree and electric field induced linear phase shift up to 330 degree.

Multiferroic heterostructure fringe field tuning of meander line microstrip ferrite phase shifter
Magnetic fringe fields emanating from a multiferroic heterostructure composite of Terfenol-D and lead magnesium niobate-lead titanate were utilized to actively tune a meander line microstrip ferrite phase shifter operating above ferrimagnetic resonance at C-band. Differential phase shifts of 65° were measured when tuned with an applied voltage to the multiferroic heterostructure. This demonstra...
