Abstract
Section titled āAbstractāAbstract Near-field enhancement of the microwave field is applied for imaging high frequency radio field using a diamond chip with an n -doped isotopically purified diamond layer grown by microwave plasma-assisted chemical vapor deposition. A short Ļ pulse length enables us to utilize a multipulse dynamic decoupling method for the detection of radio frequency field at 19.23 MHz. An extraordinary frequency resolution of the external magnetic field detection is achieved by using amplitude-shaped control pulses. Our method opens up the possibility for high-frequency-resolution RF imaging at Ī¼ m spatial resolution using nitrogen vacancy centers in diamond.
