Abstract:

A novel magnetometer utilizing a magneto-electric M-E laminate was studied. The focus of this research was to analytically and experimentally evaluate the lamination scheme to understand the magneto-electric interactions and comment on its potential for use in detection and identification of improvised explosive devices IED. A heterogeneous layered magneto-electric system composed of piezoelectric and magnetostrictive constituents were fabricated. UCLA also developed theoretical models necessary to predict magneto-electric behavior and optimize the sensitivity of the resulting material system. Based on this work, the sensitivity of a laminate is expected to exceed le-9 Gauss Analytical modeling suggests this provides defection capabilities of a 0.2 m object up to 80 m away. These highly sensitive magneto-electric laminate elements may eventually be integrated into array architectures to provide three dimensional detection at relatively large standoff distances.
