Elastic Mapping
Metamaterials are based on complicated nanopatterns grown with bottom-up processes like self-assembly of nanoparticles or top-down methods like focused ion beams and various types of lithography. The performance of these metamaterials for photonic or phononic applications can be heavily affected by structural anisotropies, defects and disorder. Thus, a very important task is the development of scanning micro-BLS for elastic mapping of complicated structures, for example, gradient colloidal glasses.
