The system utilizes the time division multiplexing (TDM) mode to detect foreign objects and the frequency sweeping resonance (FSR) mode to distinguish between MOs and LOs. Firstly, a bipolar ...

Resonant frequency shifts, measured at different resonance modes and between empty and sample-loaded cavities, were used to infer the acoustic properties of the loaded samples in the low frequency ...

Vibration and noise are two interrelated terms in the field of mechanical engineering. Vibration is caused by unbalanced inertial forces and moments whereas noise is the result of such vibrations.
