We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible in naturally occurring materials, including large imaginary components of /spl mu//sub eff/. The microstructure is on a scale much less than the wavelength of radiation, is not resolved by incident microwaves, and uses a very low density of metal so that structures can be extremely lightweight. Most of the structures are… 
Optomagnetic composite medium with conducting nanoelements
A type of metal-dielectric composites has been proposed that is characterized by a resonancelike behavior of the effective permeability μ e f f in the infrared and visible spectral ranges. This
Superconducting RF Metamaterials Made With Magnetically Active Planar Spirals
Superconducting metamaterials combine the advantages of low-loss, large inductance (with the addition of kinetic inductance), and extreme tunability compared to their normal metal counterparts.
Magnetized Plasma With Ferromagnetic Grains As A Viable Negative Refractive Index Medium
The propagation of electromagnetic waves in a cold magnetized plasma with ferromagnetic grains (MPFG) in the high frequency domain is studied theoretically. The dispersion of MPFG which is controlled
A new design of SRR operating at microwave bandwidth, parametric study
The magnetic resonators commonly called SRR are structures that exhibit a high frequency magnetic activity where natural magnetism disappears completely. Theses resonant structures with a frequency
Magnetic activity at infrared frequencies in structured metallic photonic crystals
We derive the effective permeability and permittivity of a nanostructured metallic photonic crystal by analysing the complex reflection and transmission coefficients for slabs of various thicknesses.
Homogenization near resonances and artificial magnetism in 3D dielectric metamaterials
It is now well established that the homogenization of a periodic array of parallel dielectric fibers with suitably scaled high permittivity can lead to a (possibly) negative frequency-dependent
Effective Parameters for Metamorphic Materials and Metamaterials Through a Resonant Inverse Scattering Approach
We present an inverse scattering approach for the bulk electromagnetic characterization of composite materials, based on a prior proof that artificial metallo-dielectric photonic crystals can be
Experimental realization of magnetic energy concentration and transmission at a distance by metamaterials
Concentrating magnetic energy in a desired volume is an important requirement for many technologies. Here, we experimentally realize a superconductor-ferromagnetic metamaterial that allows to


Extremely low frequency plasmons in metallic mesostructures.
A mechanism for depression of the plasma frequency into the far infrared or even GHz band is proposed: Periodic structures built of very thin wires dilute the average concentration of electrons and considerably enhance the effective electron mass through self-inductance.
Low frequency plasmons in thin-wire structures
A photonic structure consisting of an extended 3D network of thin wires is shown to behave like a low density plasma of very heavy charged particles with a plasma frequency in the GHz range. We show
3D Metallo-Dielectric Photonic Crystals with Strong Capacitive Coupling between Metallic Islands
We introduce a new type of metallo-dielectric photonic band gap structure (PBG), intentionally incorporating very strong capacitive interactions between the periodic metallic islands. The band gaps
Plasma Losses by Fast Electrons in Thin Films
The angle-energy distribution of a fast electron losing energy to the conduction electrons in a thick metallic foil has been derived assuming that the conduction electrons constitute a Fermi-Dirac
Photonic band-gap crystals
The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electron wave propagation in real crystals has proven to be a very fruitful one. Initial efforts
Inhibited spontaneous emission in solid-state physics and electronics.
If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden.
A Collective Description of Electron Interactions: II. Collective vs Individual Particle Aspects of the Interactions
The behavior of the electrons in a dense electron gas is analyzed in terms of their density fluctuations. These density fluctuations may be split into two components. One component is associated with
Calculating photonic band structure
Photonic materials structured on the scale of the wavelength of light have become the subject of an active field of research fed by the hope of creating novel properties. Theory plays a central role
3D Wire mesh photonic crystals.
An important new regime for microwave photonic crystals is identified, an effective medium limit, in which electromagnetic waves penetrate deeply into the wire mesh through the aid of an impurity band.
Collective Theory for Surface Enhanced Raman Scattering.
For the first time it is possible to handle surfaces consisting of complex particles close enough to interact strongly, and a fully retarded implementation of Maxwell's equations on adaptive meshes allows treatment of large particles as well as small.
