The authors have modeled magnetoelectric (ME) laminate sensor units by considering both the ME laminate and detection circuitry. Theory predicts and experiments confirm that the signal-to-noise ratio increases with increasing frequency in the low frequency range. Our findings provide useful insights into ME sensitivity estimation and "real-world" low frequency magnetic anomaly detection by ME sensors. (c) 2007 American Institute of Physics.
