Claim 15:
16. An apparatus for dynamic characterization of a sample of a material under test comprising:
a terahertz (THz) time-domain spectroscopy system configured and arranged to generate and detect terahertz waves to interrogate the sample;
a shock wave loading system configured and arranged to produce a shock wave in the sample;
wherein the sample undergoes changes in an index of refraction in response to the produced shock wave in the sample that are detected by the terahertz time-domain spectroscopy system during the interrogating;
wherein the shock wave loading system is an ultrafast shock wave loading system comprising a laser,
wherein the ultrafast shock wave loading system comprises a Q-switch laser having an energy of at least 0.1 J and a short pulse duration.
