We propose an artificial three-dimensional material that exhibits a strong resonance in the effective permeability in the visible spectral domain. This material may be implemented in a two-step procedure. First, a metamaterial made of densely packed metall ...
We demonstrate high spectral control from surface emitting THz Quantum Cascade Lasers based on a two-dimensional photonic crystal cavity. The perforated top metallic contact acts as an in plane resonator in a tight double-metal plasmonic waveguide providin ...
This letter reports on high extraction efficiency light-emitting diodes (LEDs) based on embedded two-dimensional air-gap photonic crystals (PhCs). High refractive index contrast provided by the air gaps along with high interaction of the embedded PhCs with ...
We use the coordinate transformation technique to design metamaterial lenses that can magnify a two-dimensional planar image beyond the diffraction limit. (C) 2008 Optical Society of America ...

As a result of the ever growing number of functionalities and standards to be supported by communication systems, as well as the constant development of radar and imaging technologies, a key research area in the field of microwaves and millimeter waves is ...
The modeling and design of metamaterial composite right/left handed transmission lines (CRLH-TL) is usually based on the assumption that its unit cell is small in terms of the host TL wavelength (d 0). However, it was also shown that this assumption is not ...
Metallic nanostructures show interesting optical properties due to their plasmonic resonances, and when arranged in three-dimensional (3D) arrays hold promise for optical metamaterials with negative refractive index. Towards this goal a simple, cheap, and ...
We apply the Ewald acceleration technique to the efficient evaluation of periodic Green's functions (GFs) for 3-D skewed lattices like those arising in electromagnetic/photonic band-gap (EBG/PBG) structures and metamaterials (MTMs). We develop the expressi ...
We demonstrate a novel approach for high-throughput and high-resolution fabrication of engineered infrared plasmonic antenna arrays with reusable nanostencils. Optical responses of these plasmonic antennas are comparable to that of arrays fabricated by ele ...
Metamaterials (MTMs) are broadly defined as artificial composite materials specifically engineered to produce desired unusual electromagnetic properties not readily available in nature. The most interesting unusual property achievable with MTMs is probably ...
