    • Enhancement in magnetic field sensitivity and reduction in equivalent magnetic noise by magnetoelectric laminate stacks 

      Li, Menghui; Gao, Junqi; Wang, Yaojin; Gray, David; Li, Jiefang; Viehland, Dwight D. (American Institute of Physics, 2012-05-15)
      We have investigated the equivalent magnetic noise and magnetic field sensitivity for a magnetoelectric (ME) sensor unit of N numbers of ME laminates stacked together. Our results show with increasing N that the modeled ...
    • Enhancing the sensitivity of magnetoelectric sensors by increasing the operating frequency 

      Petrie, Jonathan; Viehland, Dwight D.; Gray, David; Mandal, Sanjay; Sreenivasulu, Gollapudi; Srinivasan, Gopalan; Edelstein, Alan S. (American Institute of Physics, 2011-12-15)
      We present a field modulation technique that increases the operating frequency of magnetoelectric ( ME) sensors so that it can match the mechanical resonance frequency of the sensor. This not only improves the sensitivity ...
    • Shifting the operating frequency of magnetoelectric sensors 

      Petrie, Jonathan; Gray, David; Viehland, Dwight D.; Sreenivasulu, Gollapudi; Srinivasan, Gopalan; Mandal, Sanjay; Edelstein, Alan S. (American Institute of Physics, 2012-04-01)
      A method is presented for increasing the operating frequency of symmetric and asymmetric magnetoelectric (ME) sensors so that the operating frequency can be equal to the mechanical resonance frequency of the sensor. This ...
    • Theoretical analysis of the intrinsic magnetic noise spectral density of magnetostrictive-piezoelectric laminated composites 

      Zhuang, Xin; Cordier, Christophe; Saez, Sebastien; Sing, M. Lam Chok; Dolabdjian, Christophe; Gao, Junqi; Li, Jiefang; Viehland, Dwight D. (American Institute of Physics, 2011-06-15)
      The equivalent magnetic noise spectral density level for long type magnetostrictive-piezoelectric laminated composites has been investigated by using a 1D equivalent circuit model, and exemplified for a longitudinal-transverse ...
