Research on the Orthogonal Fundamental Mode Fluxgate Sensor Circuit
Currently, magnetic fluxgate circuits used for magnetic field measurements mostly adopt parallel excitation second harmonic generation. The magnetic fluxgate developed by this method cannot possess both low noise and high bandwidth at the same time.

Nonlinear dynamic responses of an inclined beam to harmonic excitation in temperature field
Abstract Using both analytical and numerical methods, nonlinear dynamic behaviours including chaotic motions and subharmonic bifurcations of an inclined beam subjected to harmonic excitation in temperature field are investigated in this paper. Based on the Galerkin method, the mathematical model of motion is derived.

Fault-Tolerant Operation of Wound Field Synchronous Machine Using Coil Switching
This paper proposes a fault tolerant operation of a wound field synchronous machine (WFSM) under the loss of excitation (LOE) fault in the rotor field winding. A two-mode field excitation scheme is presented, where the rotor of the WFSM was modified, and

Harmonic response of GMR sensor under sinusoidal excitation field
In this work, we report the readout technique of the GMR magnetometer by detecting the odd-harmonic response under an sinusoidal excitation field. The time domain output waveform of the sensor is measured, and an analytical model is used to simulate its behaviour.
