Nanostructures, local fields, and enhanced absorption in intense light-matter interaction.
Recent literature has reported impressive enhancements in hard-x-ray emission from short-lived solid plasmas by modulation of the interacting surface with nanostructures. We show that the modification of local electric fields near surface structures results in excessive absorption and enhanced x-ray production. A simple model based on local field variations explains the observed x-ray enhancements quantitatively.
