Low-Frequency Magnetic Sensing Using Magnetically Modulated Microcavity Resonant Mode

Low-Frequency Magnetic Sensing Using Magnetically Modulated Microcavity Resonant Mode

We propose a low-frequency magnetic sensing method using a magnetically modulated microcavity resonant mode. Our magnetically sensitive unit with periodically changing magnetic poles is formed by combining an AC excitation coil with a microcavity. The microcavity vibrates at the frequency of the AC...
