Abstract

A magnetic imager includes a generator for practicing a method of applying a background magnetic field over a concealed object, with the object being effective to locally perturb the background field. The imager also includes a sensor for measuring perturbations of the background field to detect the object. In one embodiment, the background field is applied quasi-statically. And, the magnitude or rate of change of the perturbations may be measured for determining location, size, and/or condition of the object. 25 figs.

Magnetic force microscopy method and apparatus to detect and image currents in integrated circuits

Patent Campbell, A N; Anderson, R E; Cole, Jr, E I

A magnetic force microscopy method and improved magnetic tip for detecting and quantifying internal magnetic fields resulting from current of integrated circuits are disclosed. Detection of the current is used for failure analysis, design verification, and model validation. The interaction of the current on the integrated chip with a magnetic field can be detected using a cantilevered magnetic tip. Enhanced sensitivity for both ac and dc current and voltage detection is achieved with voltage by an ac coupling or a heterodyne technique. The techniques can be used to extract information from analog circuits. 17 figs.

System and method using hybrid magnetic field model for imaging magnetic field sources

Patent Derego, Paul Jeffrey

A system and method for detecting a magnetic field generated by a magnetic field source located in a circuit. A magnetometer array generates data regarding an activity of the source. A computing device executes a magnetic beamforming data processing program including a hybrid model which receives data generated by the array and detects the magnetic field generated by the source. The hybrid model is based on a weighted sum of contributions to the magnetic field, which include a first modelled magnetic field contribution generated by a current dipole aligned with an axis of the source, and a second modelled magneticmore » « less
