Using a homodyne detection scheme, we show that we can determine the polarity and chirality of a magnetic vortex in an asymmetric magnetic disk as well as the resonance frequency and phase shift of the dynamic vortex gyration excited by a spin-polarized cu ...
Proposed and characterised is the use of multi-longitudinal mode Fabry-Perot laser sources, in distributed optical fibre sensors based on spontaneous Brillouin scattering, for simultaneous strain and temperature measurements. Experimental results show that ...
In this work, a complete passive UHF RFID system for capacitive sensing applications is developed to be used in food quality monitoring and supply chain management. All the components of the RFID system including the base station, the base station antenna, ...
Microfluidic diagnostic devices have the potential to transform the practice of medicine. We engineered a multiplexed digital-analog microfluidic platform for the rapid and highly sensitive detection of 3-4 biomarkers in quadruplicate in 16 independent and ...
A distributed temperature sensor based on spontaneous Brillouin scattering and employing optical pulse coding has been implemented and characterized using a direct-detection receiver. The signal-to-noise ratio (SNR) enhancement provided by coding is analyz ...
