When calibrated with a Gauss probe, the magnetic dipole probe was insensitive to electrical field whilst it detected the magnetic area higher than the magnetized ferromagnetic sample with 1% precision and 0.06% resolution at 2 GHz. Employing a simplified circuit model from the resonator, we have been able to interpret http://waferprobing01234.fireblogz.com/22953741/wafer-probing-options
