High-power calibration and measurement method for bio-electromagnetic study

Abstract

A novel method for high-power calibration/measurement is presented in this work. This method employs a coupler and a dipole antenna to achieve high-power measurement. The coupler serves as a low-power sensor, whereas the dipole antenna is responsible for the high-power measurement. This method successfully calibrated a 600 W 13.56 MHz radio frequency generator and is potentially useful for even higher power measurement, as well as for hazardous high-intensity electromagnetic environment measurement, avoiding the use of expensive high-power metres.
