This paper covers the following: * All-Optical Light Modulation of surface plasmon polaritons (SPPs) is achieved using asymmetric single nanoslits. A high on/off switching ratio of >20 dB and phase variation of >? were observed with the device lateral dimension of only about 2 ?m. * Efficient unidirectional excitation of SPP as well as beam splitting are achieved using the ...

The silicon cantilever with the planar coil was applied to the magnetic flux density measurements. The influence of shape and dimensions of planar coil on magnetic energy density was described. In cause of magnetic anisotropy of analyzed silicon structure FEM method and couple field method was applied in simulation. The Lorentz force based sensors owing to their potentially simpler fabrication ...

Small electronic devices are nowadays used in varying conditions, which expose them to stresses. One part of this stress is related to transport of potentially harmful chemical substances into small mechanical structures of devices, which happens by molecular diffusion and advection by air flow. We have applied a simplified contamination model, whose parameters, though, are estimated by ...

This note addresses the concept of wave energy conversion by means of a piezoelectric material. The ocean surface waves represent an important source of energy. A multiphysics simulation is used to focus on different aspects, namely the free surface wave, the fluid-structure interaction, the mechanical energy input to the piezoelectric material and the electric power output, using an equivalent ...

A successful development of an effective quench detection and protection method for a high temperature superconducting (HTS) coil based on a HTS coated conductor tape lays on a thorough understanding of its slowly propagating, three-dimension (3D) quench behavior. Toward this goal, a 3D micrometer scale finite element (FE) thermo-magnetostatic HTS tape model is developed and implemented in ...

A fundamental understanding of the transport phenomena in microfluidic channels is critical for systematic design and precise control of such miniaturized devices towards the integration and automation of Lab-on- a-chip devices. Electroosmotic flow is widely used to transport and mix fluids in microfluidic systems. Electroosmotic transport in convergent divergent micronozzle is significant in ...

Porous Silicon (PS) can easily be formed by electrochemical etching of silicon in HF based electrolytes at room temperature. Since, PS is compatible with silicon IC technology; it finds lot of applications in the fabrication of MEMS devices. In the current study, we discuss the design of a condenser microphone using a Silicon/ Porous Silicon composite membrane as a movable plate. The performance ...
In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.

A small particle or a nano-sized object placed in a liquid is subject to random collisions with solvent molecules. The resulting erratic movement of the object is known as Brownian motion, which, in nature, cannot be used to any practical advantage both in natural systems (such as biomolecular motors) or by artificial devices. If energy is supplied by external source or by chemical reactions, ...

In this work, a system for magnetic and hydrodynamic manipulation of magnetic beads is modelled. A geometry is introduced to assure a good separation behaviour with respect to the magnetic moment of the particles. Different separation mechanisms will be discussed and an estimation of the minimal difference of separable magnetic moments will be given. Further it will be shown, that the ...
