We propose to model periodic structures by equivalent multiconductor transmission lines (MTLs). The developed technique is based on a multimodal representation of the periodic structure unit cell, such as required for periodically loaded MTLs and periodica ...
Dynamic reconfiguration of a microwave photonic filter by tuning its basic delay based on stimulated Brillouin scattering-induced slow light and optical phase shift of the optical carrier is experimentally implemented. The measurements confirm that the fre ...
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 ...
Cloaking using a volumetric structure composed of stacked two-dimensional transmission-line networks is verified with numerical simulations and measurements. The measurements are done in a waveguide, in which an array of metal cylinders is inserted causing ...
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 ...
We demonstrate that the tunable potential introduced by a surface acoustic wave on a homogeneous polariton condensate leads to fragmentation of the condensate into an array of wires which move with the acoustic velocity. Reduction of the spatial coherence ...
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 ...

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 ...
An artificial transmission line unit cell is presented based on the so-called composite right/left handed transmission line. It is implemented on a microelectromechanical system process on glass, and is suitable for applications such as reconfigurable leak ...
The manuscript reports the outcome of investigations on the phononic properties of a chiral cellular structure. The considered geometry features in-plane hexagonal symmetry, whereby circular nodes are connected through six ligaments tangent to the nodes th ...
