Generation of nearly pure and highly directional magnetic light in fluorescence of rare earth ions
Anton D. Utyushev, Roman Gaponenko, Song Sun +3
A thorough analysis of the emission via the magnetic dipole (MD) transition, called magnetic light below, of trivalent rare-earth ions in or near dielectric homogeneous spheres has…
Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
Bound states in the continuum in photonic structures
Kirill Koshelev, Zarina Sadrieva, Alexey Shcherbakov +2
Bound states in the continuum provide a remarkable example of how a simple problem solved about a century ago in quantum mechanics can drive the research on a whole spectrum of res…
