All-dielectric metamaterials: simulation of nanorod and arrays

Abstract

ABSTRACTIn this work, scattered electric and magnetic fields of all-dielectric metamaterials were derived using a commercial RF finite-element partial differential equations solver. We present the implementation of rod-type composites consisting of a mixture of two components: the first one, which is called guest, is made of Ba1-xSrxTiO3 (0 ≤ x ≤ 1) and the second one, the host, made of SiO2. Analysis includes both the scattering effect, well described by the MIE theory, and dielectric inhomogeneous structure properties, determined using the MAXWELL-GARNETT approximation.
