Two-dimensional phononic-photonic bandgap optomechanical crystal cavity [PDF]

, 2014
We present the fabrication and characterization of an artificial crystal structure formed from a thin-film of silicon which has a full phononic bandgap for microwave X-band phonons and a two-dimensional pseudo-bandgap for near-infrared photons.

Tamm states in one dimensional photonic crystals containing left-handed materials [PDF]

, 2006
We present a theoretical study of electromagnetic surface waves localized at an interface separating a conventional uniform medium and a semi-infinite 1-D photonic crystal made of alternate left-handed metamaterial and right-handed material which we ...

The Crystal Structure of Monovalent Streptavidin. [PDF]

, 2016
The strong interaction between streptavidin (SA) and biotin is widely utilized in biotechnological applications. A SA variant, monovalent SA, was developed with a single and high affinity biotin-binding site within the intact tetramer.

Manifestation of photonic band structure in small clusters of spherical particles [PDF]

, 2002
We study the formation of the photonic band structure in small clusters of dielectric spheres. The first signs of the band structure, an attribute of an infinite crystal, can appear for clusters of 5 particles.
