Abstract
Metamaterials offer an ideal platform to test quantum interactions with free electrons, and in addition, they can be designed to mould the quantum wave function of electron beams. In this talk, we discuss recent advances in our understanding of quantum effects associated with the interaction between free electrons and optical modes in nanomaterials. We then focus on optical modes in metamaterial and their interaction with free electrons, based on which we present optimum structures for free-electron shaping with the purpose of performing electron microscopy with improved spectral/spatial/temporal resolution in the sub-meV/sub-nm/sub-fs range.
