Transfer Impedance of SMA Receptacle as Wideband Measurement Electrode for Discharge Current from Charged Human

We have derived a transfer impedance of an SMA receptacle as a wideband measurement electrode being used for discharge currents from a charged human, and have measured its frequency characteristics from 300 kHz to 20 GHz. With a 12 GHz digital oscilloscope, measurement of discharge currents through a hand-held metal bar from a charged human was also made, and thereby the injected currents on the SMA receptacle were reconstructed from the measured transfer impedance.
