When CdSe/CdS core/shell quantum dots QDs are dispersed onto a two-dimensional 2D textured Ag grating, their luminescent behavior is dramatically modified. Excited QDs can resonantly excite surface plasmon polaritons SPPs propagating along the modulated metallic surface. The measurements of PL spectra and time-resolved PL spectra clearly indicate the interaction between QDs and 2D SPPs. The ele...

In this paper the effect of corrugated diaphragm on performance of MEMS microphone is described. The corrugated diaphragm is modeled in order to improve the sensitivity of micromachined silicon acoustic sensor. Analytical analyzes have been carried out to derive mathematic expressions for the mechanical sensitivity and displacement of corrugated diaphragm with residual stress. It is shown that ...

We investigate the performance of a simple corrugated aperture scanning near-field optical microscope (SNOM) probe with various cladding metals. The probes have only one corrugation, however, they offer increased transmission over both uncorrugated probes and those with many grooves. Enhancement of light throughput results from excitation of surface plasmons at the corrugation at the core-cladd...

In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...

In this study the effects of corrugated absorber plate and using aerosol-carbon black nanofluid on heat transfer and turbulent flow in solar collectors with double application and air heating collectors, were numerically investigated. The two-dimensional continuity, momentum and energy equation were solved by finite volume and SIMPLE algorithm. In the present investigation all the simulations w...

We report on a new synthesis method of reflection filters with multilayer and waveguide structures. The filter is characterized by bandwidth as small as ≤ 1 nm for effective use in wavelength-division-multiplexed optical communications. Both the transfer-matrix method and the Fourier transformation are employed to determine the filter reflection from a spatially varying refractive index. In con...

Periodic cellular metals with honeycomb and corrugated topologies are widely used for the cores of light weight sandwich panel structures. Honeycombs have closed cell pores and are well suited for thermal protection while also providing efficient load support. Corrugated core structures provide less efficient and highly anisotropic load support, but enable cross flow heat exchange opportunities...
