Generalized Kerker effect in dielectric resonant antennas for enhanced backscattering modulation
Abstract
My talk will be devoted to the development of a subwavelength antenna model, which provides high efficiency of RFID tags. The key parameter to be optimized is the modulation of the backscattering signal. It will be demonstrated that combining high refractive index dielectric materials with tunable subwavelength resonators achieves efficient modulation of the signal scattered towards the source. The considered layered spherical structure supports Mie resonances, the interference between which leads to either amplification or decreasing of backscattering, known as the generalized Kerker effect.
