FYI: Terahertz radiation can induce insulator-to-metal change of state in some materials
http://phys.org/news/2012-07-terahertz-insulator-to-metal-state-materials.ht ml "the researchers used an antenna-like structure called a split ring resonator to concentrate the electric field of a THz pulse in a small area, increasing the electric field from hundreds of kilovolts per centimeter to about 4 megavolts per centimeter." Is there anything about H-loaded metals with shallow fractures, or Ni tubercles, which might act like a split-ring resonator? ".because THz frequencies match the resonant frequencies at which neighboring atoms and molecules in crystal lattices vibrate against each other, *THz pulses can drive the lattice vibrations directly*-possibly to large amplitudes. THz light can drive electrons and whole atoms and molecules far from their equilibrium locations in a crystal lattice, which can lead to phase transitions in electronic state and/or crystal structure." -Mark Iverson
