Improved calibration method for the extension of the existing magnetic field calibration capability in Helmholtz coils from 3 MHz to 10 MHz or higher
Original language description
The research presented in this report includes the design, fabrication and characterisation of the Helmholtz coils setup up to 10 MHz using various methods. For this purpose, a single-turn shielded small loop antenna and commercial magnetic field probes are used and the results are compared. In addition, to use loop antennas as a calibration transfer standard, the magnetic antenna factors obtained by different calibration methods of loop antennas are compared by including the uncertainty budget of each method. As a result of the evaluation, the magnetic antenna factors obtained by the impedance method of small loop antennas were used to calibrate the magnetic field strength indicated in Helmholtz coils.
