in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

We present new results on the optical link for the pixel detector of the ATLAS experiment. An optical package of novel design has been developed for the opto-link. The design is based on a simple connector-type concept and is made of radiation-hard material. The receiver (DORIC) and transmitter (VDC) chips have been designed. The prototype results using the 0.8 and 0.25 μm technologies are pres...

sr6nb10o30–nb2o5 nanocomposite was synthesized in 2m naoh aqueous solution. a stoichiometric 1:1 sr:nb molar ratio hydrothermal method at 120°c was used to synthesize this nanocomposite. sr(no3)2 and nb2o5 were used as raw materials. the synthesized nanomaterials were characterized by powder x-ray diffraction (pxrd) technique. it was found that sr6nb10o30 was crystallized in tetragonal crystal ...

This paper presents an experimental investigation on mode I delamination of z-pinned double-cantilever-beams (DCB) and associate z-pin bridging mechanisms. Tests were performed with three types of samples: big-pin with an areal density of 2%, small-pin with an areal density of 2% and small-pin with an areal density of 0.5%. The loading rates for each type of samples were set at 1 mm/min and 100...

This paper introduced planning and control of a hybrid vacuum-forming machine system (HAVES). The HAVES was developed to integrate CAD/CAM, screw-pin tooling, CNC, vacuum forming and optical measurement device together to produce vacuum forming components. The screw-pin tooling was employed to replace traditional dedicated solid tooling and its reconfigurability provided the HAVES with advantag...

An optical package of novel design has been developed for the ATLAS pixel detector. The package contains two VCSELs and one PIN diode to transmit and receive optical signals. The design is based on a simple connector-type concept and is made of radiation-hard material. Several packages have been fabricated and show promising results.

The plasmonic resonance frequency of metal nanoparticles (NPs) strongly depend on the geometry, size, and separation between NPs. Here, a structure is designed based film-coupled nanoparticle phenomenon analytically investigated by finite element method via COMSOL Multiphysics software tool. optical behavior studied compared for two noble metals (gold silver as case study). Simulation results c...

Most models of biological pattern formation are simulated on continuous domains even though cells are discrete objects that provide internal boundaries to the diffusion of regulatory components. In our previous papers on simulating organogenesis in COMSOL (Germann et al COMSOL Conf Procedings 2011; Menshykau and Iber, COMSOL Conf Proceedings 2012) we discussed methods to efficiently solve signa...
