Generalized Kerker effect in dielectric antennas for enhanced backscattering modulation

Abstract

Abstract Enhancement of electromagnetic signal modulation is one of the key problems for modern contactless communication systems. Using resonance effects allows to achieve significant interaction between an electromagnetic wave and matter of an antenna, providing opportunity to control scattering. This work demonstrates efficiency of multipole engineering based on Mie theory for dielectric core-shell antennas, particularly we show that generalized Kerker effect is a useful tool for backscattering modulation magnification. Our approach allows to manipulate scattering properties of devices without increasing their size by using all-dieletric concept.
