Inelastic Scattering of Electron Beams by Nonreciprocal Nanotructures
Renwen Yu, Andrea Konečná, F. Javier García de Abajo
Probing optical excitations with high resolution is important for understanding their dynamics and controlling their interaction with other photonic elements. This can be done usin…
Revealing Nanoscale Confinement Effects on Hyperbolic Phonon Polaritons with an Electron Beam
Andrea Konečná, Jiahan Li, James H. Edgar +2
Hyperbolic phonon polaritons (HPhPs) in hexagonal boron nitride (hBN) enable the direct manipulation of mid-infrared light at nanometer scales, many orders of magnitude below the f…
Optical Modulation of Electron Beams in Free Space
F. Javier García de Abajo, Andrea Konečná
We exploit free-space interactions between electron beams and tailored light fields to imprint on-demand phase profiles on the electron wave functions. Through rigorous semiclassic…
Electron Beam Aberration Correction Using Optical Near Fields
Andrea Konečná, F. Javier García de Abajo
The interaction between free electrons and optical near fields is attracting increasing attention as a way to manipulate the electron wave function in space, time, and energy. Rely…
Plasmonic antennas with electric, magnetic, and electromagnetic hot spots based on Babinet's principle
Martin Hrtoň, Andrea Konečná, Michal Horák +2
We theoretically study plasmonic antennas featuring areas of extremely concentrated electric or magnetic field, known as hot spots. We combine two types of electric-magnetic comple…
