Sensing Magnetic Field with Light and Nanomechanics
conference on lasers and electro optics（2021）
摘要
We demonstrate an optical magnetic field sensor based on a metamaterial-microcavity. Actuation of the microcavity by the magnetic Lorentz force controls its reflectivity. Such sensors promise microscale spatial, millisecond temporal and microtesla magnetic field resolution.
