Latest Patents

One of her latest patents is focused on the cancellation of ringing artifacts and far-field interference in nuclear quadrupole resonance. This invention involves a device designed to detect a class of target species containing quadrupolar nuclei in a specimen by utilizing nuclear quadrupole resonance. The device comprises a pulse generator that creates a three-pulse-composite-pulse to refocus signals excited by another pulse, an irradiator for applying this pulse to the specimen, a detector for capturing the NQR signal, a coupler for transmitting the pulse, and a transformer for converting the free induction decay signal into a frequency domain signal.

Another notable patent is the subfemtotesla radio-frequency atomic magnetometer for nuclear quadrupole resonance detection. This invention features a radio-frequency tunable atomic magnetometer capable of detecting nuclear quadrupole resonance from room temperature solids. It includes the detection of nitrogen-containing explosives placed external to a sensor unit. The potassium radio-frequency magnetometer operates with a sensitivity of 0.24 fT/Hz at 423 kHz, marking a significant achievement in the field. This technology demonstrates the first-time detection of NQR with an atomic magnetometer, highlighting its potential as a new tool for detecting magnetic resonance signals in the kHz to MHz range.
