Surface Plasmons in Thin Films
The dispersion relations for surface plasma oscillations in normal metals are investigated for single- and multiple-film systems taking retardation effects into account. The simple dielectric…

Electric coupling to the magnetic resonance of split ring resonators
We study both theoretically and experimentally the transmission properties of a lattice of split ring resonators (SRRs) for different electromagnetic (EM) field polarizations and propagation…

Left-handed metamaterials: The fishnet structure and its variations
We investigate, both theoretically and experimentally, a left-handed metamaterial design composed of pairs of short slabs connected with continuous wires, operating in microwave frequency regime. The…

Multiple-scattering theory for three-dimensional periodic acoustic composites
We present results for acoustic wave propagation in periodic composites consisting of solid spheres in a fluid host. We show that for solid scatterers in fluid host material combinations the…

Refraction in media with a negative refractive index.
We show that an electromagnetic (EM) wave undergoes negative refraction at the interface between a positive and negative refractive index material, the latter being a properly chosen photonic…

Elastic waves in plates with periodically placed inclusions
We calculated the frequency ω versus the wave vector K for elastic waves propagating in both thick and thin plates consisting of solid inclusions placed periodically in the host material. We were…

Effective medium theory of left-handed materials.
TLDR
The SRRs have a strong electric response, equivalent to that of cut wires, which dominates the behavior of left-handed materials (LHM), which can be used to explain the transmission characteristics of LHMs.
