Low frequency EDMR with broadband antenna loop: (a) BM EDMR with RF between \(\nu \) = 2 MHz and \(\nu \) = 250 MHz. The signal is dominated by the standard ZFSDR signal. (b) AM EDMR with different frequencies between \(\nu \) = 2 MHz (light green) and \(\nu \) = 250 MHz (dark green)to reveal only the RF involved transitions. The peaks are damped by the ZFSDR leakage (pink) and the high impedance of the loop antenna due to its high inductance (black). (c) and (d) peak amplitude of BM and AM, respectively. The broadband antenna is most efficient at \(\nu =50~\text {MHz}\) which is used for low frequency proof of concept measurements.
