Latest Patents

Among his latest patents is a groundbreaking invention titled "Ferrite resonators using magnetic biasing and spin precession." This patent describes a low loss unidirectional conductive sheet that utilizes magnetic field biasing and electron spin precession to couple RF power to ferrite resonators. The process involves placing multiple ferrite resonators in a bias magnetic field to excite the electron spins of the materials into precession.

Another significant patent is the "Differential resonant ring oscillator utilizing magnetically tuned YIG resonators to achieve ultra low phase noise and multi-octave electronic tuning in microwave frequencies." This invention outlines a differential resonant ring oscillator (DRRO) circuit that employs a ring oscillator topology to electronically tune the oscillator over multi-octave bandwidths. The tuning is linear, as the oscillator frequency is related to the magnetic tuning of a YIG sphere, which resonates at a frequency determined by the DC magnetic field. The circuit utilizes half turn or multiple half turn loops for magnetic coupling, connecting a differential pair of amplifiers in a feedback loop configuration with a four-port YIG tuned filter.
