This paper aims to designed a prototype for achieving the full magnetostriction of Galfenol, Lamination struction of transducer is designed and the radiation impedance is expressed in mechanical terms, a simplified onedimensional modeling of SPICE magnetostrictive transducer is established, the electrical input impedance is simulated as the function of frequency and experimentally adjusting the values is to match an existing impedance curve. a good fit between model and measurement is shown by
