Microwave Imaging

In the following work, the team led by Patrick Maletinsky uses a Quantilever MX prototype to map the high frequency current (GHz) flowing in a prototype electronic circuit. The magnetic field generated by the current is imaged quantitatively with a shot noise limited sensitivity of 680 nT/Hz1/2and deep sub-wavelength spatial resolution (10-6 * signal wavelength).
