Latest Patents

One of his latest patents is the "Scanning SQUID microscope with improved spatial resolution." This invention involves a scanning SQUID microscope designed to acquire spatially resolved images of the physical properties of an object. The SQUID sensor is arranged perpendicularly to the plane of the object, allowing for the detection of the tangential component of the magnetic field generated by the object. The processing unit interprets the position signal and relevant output signals from the SQUID sensor to derive spatially resolved images. The specific orientation of the SQUID sensor enhances the area of the SQUID chip, facilitating lower contact resistance and easier connections with bias and read-out wires.

Another significant patent is "Imaging using spatial frequency filtering and masking." This method and apparatus create images of currents flowing through microelectronic circuits with improved spatial resolution. The filters used in this invention enhance spatial resolution while eliminating noise and edge artifacts in magnetic and electric field images. The technique involves creating a magnetic field image with a scanning SQUID microscope and using a magnetic inversion technique to convert it into a current density image. This method can also be applied to convert electric fields from a scanning single electron transistor microscope into voltage level images on circuit wires.
