Photonic Crystals and Resonators

In recent years, artificial optical materials and structures enabled the observation of various new optical effects and experiments. For example, photonic crystals are able to inhibit the propagation of certain light frequencies and provide the unique ability to guide light around very tight bends and along narrow channels. On the other hand, the high field strengths in optical microresonators ...

Recent Developments in Sonic Crystals

The properties of sonic bandgap crystals will be reviewed and recent results obtained by our group will be reported. Particularly, the homogenization method based on multiple scattering theory will be presented and applied to the case of two-dimensional (2D) structures consisting of fluid-fluid and solid-fluid composites [1, 2]. The method is general and it is employed to get the effective para...

Superparamagnetic Photonic Crystals

tion. Conversely, a semi-rigid, optimized acentric organization results in coherent second harmonic emission at the supramolecular level, the corresponding intensity from the dendrimer solution being almost proportional to Nmonomerábmonomerñ. The Nmonomer dependence assumes a linear additive model, whereby the individual sub-units follow an interaction-free oriented gas behavior. We have, there...
