Extension of Friedel's law to Vortex Beam Diffraction
Roeland Juchtmans, Giulio Guzzinati, Jo Verbeeck
Friedel's law states that the modulus of the Fourier transform of real functions is centrosymmetric, while the phase is antisymmetric. As a consequence of this, elastic scattering…
Probing the symmetry of the potential of localized surface plasmon resonances with phase-shaped electron beams
Giulio Guzzinati, Armand Béché, Hugo Lourenço--Martins +3
Plasmonics, the science and technology of the interaction of light with metallic objects, is fundamentally changing the way we can detect, generate and manipulate light. Although t…
Investigation into spiral phase plate contrast in optical and electron microscopy
Roeland Juchtmans, Laura Clark, Axel Lubk +1
The use of phase plates in the back focal plane of a microscope is a well established technique in optical microscopy to increase the contrast of weakly interacting samples and is…
