Poynting singularities in the transverse flow-field of random vector waves
M. A. van Gogh, T. Bauer, L. De Angelis +1
In order to utilize the full potential of tailored flows of electromagnetic energy at the nanoscale, we need to understand its general behaviour given by its generic representation…
Screening and fluctuation of the topological charge in random wave fields
L. De Angelis, L. Kuipers
Vortices, phase singularities, and topological defects of any kind often reflect information that is crucial for understanding physical systems in which such entities arise. With n…
Persistence and Lifelong Fidelity of Phase Singularities in Optical Random Waves
L. De Angelis, F. Alpeggiani, A. Di Falco +1
Phase singularities are locations where light is twisted like a corkscrew, with positive or negative topological charge depending on the twisting direction. Among the multitude of…
Spatial Distribution of Phase Singularities in Optical Random Vector Waves
L. De Angelis, F. Alpeggiani, A. Di Falco +1
Phase singularities are dislocations widely studied in optical fields as well as in other areas of physics. With experiment and theory we show that the vectorial nature of light af…
