Abstract

Magnetic field distributions were measured for test stripline structures with anisotropic magnetoresistive (AMR), thin film Permalloy sensors. Linear arrays of eight barber-pole-type AMR sensors were used to increase the speed of the imaging and stability of scanning. The magnetic field distributions were converted to the distribution of electric current density in a stripline by inverting Maxwell's equations.
