Shock-Induced Polarization in Polar Materials
Several authors [1–4] have shown that polar materials become polarized by the passage of an intense shock wave. The experimental arrangement is shown in Fig. 1. The polar material is the dielectric of a parallel-plate capacitor. An explosive charge is detonated next to one electrode and the shock transmitted into the dielectric causes a current to flow through the resistance connected to the electrodes. A typical current-time polarization signal is shown in Fig. 2.
