Abstract

Just as natural materials derive their properties from those of their constituent atoms and molecules, artificial metamaterials derive their properties from those of their nanoengineered unit cells. We have developed novel methods for visualizing the localized field-enhancements of plasmonic metamaterials’ unit cells. Based on the use of ultrafast laser pulses, these methods combine user-friendliness and high resolution.
