Abstract :
The presented numerical results reveal important details of the injection-locked operation of the gyro-BWO and its dependence on the external magnetic field. Increasing the magnetic field leads to an operating frequency jump due to the excitation of the undesired taper mode which reduces the magnetic tuning bandwidth. Moreover, significant modifications of the locking bandwidth curve have been observed when the magnetic field is tuned.
