英文摘要： Advanced technology for magnetic field measurement is very important for the development of internet-of-things, especially for the smart grid. Based on the frontier of international research, the requirements of practical applications and some findings from previous studies by other researchers and ourselves, this project is proposed to study the basic physical principles of the interaction between magnetic fluid and optical fibers, as well as their applications in magnetic field sensing applications. We will carry out both the theoretical and experimental studies to discover the action mechanism of magnetic fluid to evanescent wave of optical fibers through the magnetic field controlled orientation and clustering of magnetic nanoparticles that disperse in magnetic fluid, and ahcieve the theoretical analysis mode. Furthermore, a high performance magnetic fluid-infiltrated microstructured optical fiber tilt grating-based magnetic field sensor, together with its demodulation, multiplexing and networking technologies, is proposed to study. It will be designed by combining the advanced microstructured optical fiber technology, fiber grating technology, optofluidic technology and innovitive sensor design ideas. The new technology is expected to be used in the rapidly-developed smart grid systems and other related areas of internet-of-things.
