All-dielectric nanoantennas

Belov, Pavel A; Krasnok, AE; Simovski, Constantin; Miroshnichenko, Andrey; Kivshar, Yuri


We propose a new type of highly efficient Yagi-Uda nanoantenna and introduce a novel concept of superdirective nanoantennas based on dielectric nanoparticles. In addition to the electric response, these dielectric nanoantennas exhibit very strong magnetic resonances at the nanoscale. Both types of nanoantennas are studied analytically, numerically and exper- imentally. For superdirective nanoantennas we also predict the effect of the beam steering at the nanoscale characterized by a...[Show more]
