MEASUREMENTS OF THE COMPLEX PERMITTIVITY OF ACID-DOPED ICE FROM 1 KHZ TO 30 MHZ : NEW DATA SET FOR DEVELOPING ICE RADAR AND DIELECTRIC ANALYSIS OF ICE CORES
We measured the complex permittivity of pure and acid (HCl, HNO_3 and H_2SO_4)-doped ice from 1 kHz to 30 MHz and from -9℃ to -33℃. The complex permittivity of acid-doped ice is assumed to depend linearly on the concentration. The frequency and temperature dependence of the relationship between the...
