Ultracompact all-dielectric superdirective antennas: Theory and experiment

Krasnok, AE; Belov, Pavel A; Filonov, Dmitry S; Simovski, Constantin; Slobozhanyuk, A P; Kivshar, Yuri


We demonstrate a simple way to achieve superdirectivity of electrically small antennas based on a spherical dielectric particle with a notch. We predict this effect theoretically for nanoantennas excited by a point-like emitter located in the notch, and t
