Magnetoinductive polaritons: Hybrid modes of metamaterials with interelement coupling
A theory is presented combining effective-medium theory with that of magnetoinductive (MI) waves propagating by virtue of coupling between the resonant elements. The resulting circuit equations for the split-ring resonator (SRR) loaded transmission line are shown to be analogous to those describing a continuous anisotropic magnetic plasma exhibiting spatial dispersion due to interelement coupli...
متن کاملNonlocal effective medium analysis in symmetric metal-dielectric multilayer metamaterials
The optical nonlocality in symmetric metal-dielectric multilayer metamaterials is theoretically and experimentally investigated with respect to transverse-magnetic-polarized incident light. A nonlocal effective medium theory is derived from the transfer-matrix method to determine the nonlocal effective permittivity depending on both the frequency and wave vector in a symmetric metal-dielectric ...
متن کاملA Symmetrical Circuit Model Describing All Kinds of Circuit Metamaterials
We present a generally symmetrical circuit model to describe all kinds of metamaterials with effective permittivity and permeability. The model is composed of periodic structures whose unit cell is a general T-type circuit. Using the effective medium theory, we derive analytical formulations for the effective permittivity and effective permeability of the circuit model, which are quite differen...
متن کاملNear-infrared surface plasmon polariton dispersion control with hyperbolic metamaterials.
We demonstrate experimentally signatures and dispersion control of surface plasmon polaritons from 1 to 1.8 µm using periodic multilayer metallo-dielectric hyperbolic metamaterials. The fabricated structures are comprised of smooth films with very low metal filling factor. The measured dispersion properties of these hyperbolic metamaterials agree well with calculations using transfer matrix, fi...
متن کاملArtificial Magnetic Properties of Dielec- Tric Metamaterials in Terms of Effective Circuit Model
An effective series RLC model for the electromagnetic response of weakly absorbing dielectric sphere near the first magnetic dipole resonance was developed, and the effective magnetic properties of Mie resonance-based dielectric metamaterials were obtained in terms of this model. In comparison with traditional effective medium theory such as extended Maxwell-Garnett (EMG) theory based on Mie mo...
