Abstract
Electromagnetic radiation of a nanoantenna formed by a magnetic-current filament of infinite length and an electrically thin multilayer gyrotropic cylindrical scatterer in the surrounding free space is studied. It is shown the possibility to achieve simultaneously high directivity of radiation and the desired direction of the main lobe of the antenna radiation pattern by choosing the parameters of the layers of the gyrotropic cylinder. It is demonstrated that the radiation field of such an antenna in the far zone has a nonzero angular momentum with respect to the cylinder axis. A comparison is made between the radiation characteristics of such an antenna and the radiation characteristics of an antenna of similar geometry with isotropic filling of a multilayer cylindrical scatterer.
