Time- and frequency-domain study for electron beams penetrating dielectric nanospheres: fingerprints of Cherenkov and transition radiation
Wenhua Zhao, Christos Tserkezis, N. Asger Mortensen +1
We present a theoretical study of Cherenkov and transition radiation for swift electron beams penetrating dielectric nanospheres using material models of different sophistication.…
Relativistic electron energy-loss spectroscopy in cylindrical waveguides and holes
Álvaro Rodríguez Echarri, Wenhua Zhao, Kurt Busch +1
Swift electrons passing near or through metallic structures have proven to be an excellent tool for studying plasmons and other types of confined optical modes involving collective…
Real-time surface plasmon polariton propagation in silver nanowires
Wenhua Zhao, Álvaro Rodríguez Echarri, Alberto Eljarrat +7
Electron microscopy techniques such as electron energy-loss spectroscopy (EELS) facilitate the spatio-spectral characterization of plasmonic nanostructures. In this work, a time-de…
Electron beams traversing spherical nanoparticles: analytic and numerical treatment
P. Elli Stamatopoulou, Wenhua Zhao, Álvaro Rodríguez Echarri +4
We present an analytic, Mie theory-based solution for the energy-loss and the photon-emission probabilities in the interaction of spherical nanoparticles with electrons passing nea…
