Such an all-dielectric nanoantenna can be realized as an optically small spherical dielectric nanoparticle with a notch excited by a point source located in the notch. We also confirm the predicted superdirectivity effect experimentally through scaling to the microwave frequency range.enPublisher Copyright: © Published under licence by IOP Publishing Ltd.201410.1088/1757-899X/67/1/01200884908529849
