Magnetic and electric coupling effects of dielectric metamaterial
The coupling effects of subwavelength high-permittivity (εr > 100) arrayed ceramics which exhibit magnetic and electric Mie resonances are investigated by electromagnetic full-wave analysis. Special attention was paid to the symmetry properties of both magneticand electric-induced dipoles by varying independently the array periodicity. In agreement with the interactions between electric and mag...
متن کاملTunable Dielectric Properties of Ferrite-Dielectric Based Metamaterial
A ferrite-dielectric metamaterial composed of dielectric and ferrite cuboids has been investigated by experiments and simulations. By interacting with the electromagnetic wave, the Mie resonance can take place in the dielectric cuboids and the ferromagnetic precession will appear in the ferrite cuboids. The magnetic field distributions show the electric Mie resonance of the dielectric cuboids c...
متن کاملMagnetically Tunable Ferrite-Dielectric Left-Handed Metamaterial
In this paper, a magnetically tunable metamaterial is proposed and studied. The metamaterial is based on the combination of ferrite sheets and dielectric rods. The tunable property is originated from the ferromagnetic resonance and electric response of dielectric rods. The retrieved electromagnetic parameters and transmission characteristic showed that by simultaneously inspiring the ferromagne...
متن کاملInfluence of randomness on the effective dielectric function of metal-dielectric composites for metamaterial purposes
The effective dielectric function of metal-dielectric composites consisting of spherical particles randomly distributed in a matrix is numerically investigated. The study, based on the spectral density theory, shows that local field fluctuations may critically affect the composite performance for metamaterial applications. It appears that randomness significantly modifies the effective dielectr...
متن کاملOn the dielectric function tuning of random metal-dielectric nanocomposites for metamaterial applications.
The potential of random metal-dielectric nanocomposites as constituent elements of metamaterial structures is explored. Classical effective medium theories indicate that these composites can provide a tunable negative dielectric function with small absorption losses. However, the tuning potential of real random composites is significantly lower than the one predicted by classical theories, due ...
