The unique optical properties of plasmon resonances in noble metal nanoparticles have been extensively investigated owing to their ability to enhance the electric field amplitude but also to tailor its spectral and spatial distribution. Among all application domains, nonlinear optics play a singular role since the efficiency of the underlying physical processes are driven by specific symmetry ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we ...

A high performance MEMS Pirani sensor (VAC_03) was designed and optimized based on analytics. Due to the fact that this MEMS Pirani sensor is a 3D-Object, the calculation of the thermal radiation by analytics is limited. As the radiation behavior in the system is, beside the solid thermal conductance, responsible for the low-pressure detection limit of such vacuum gauges, we switched to a FEM ...

Energy harvesting from ambient vibrations has become an interesting topic for powering wireless sensor networks. Resonant microdevices based on MEMS have become of central importance at low frequency. The power produced at resonance is at least one order of magnitude larger than off frequency power since the largest strain is obtained at resonance. In order to obtain large strain for efficient ...

As a part of a lab-on-chip-device, more often it is required to measure dielectric constant of the fluid. For this purpose it is necessary to develop a sensor whose size is compatible with microfluidic channel. The work, presented in this paper, studies effect of the parameters influencing sensitivity of such a sensor and ultimately optimizes these dimensions to maximize the sensitivity. We ...

Adulteration of automobile fuels, especially petrol and diesel is a rampant malpractice in India. With the rising prices of fuel and the subsidy on kerosene, getting away with even 10-15% adulteration is immensely profitable.To check adulteration effectively, it is necessary to monitor the fuel quality at the distribution point itself. The equipment for this purpose should be handy and the ...

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal parameters for the longest displacement. Our current micro fabrication process allows the actuator to use ...

The piezoresistance effect is defined as change in resistance due to applied stress. Silicon has a relatively large piezoresistance effect which has been known since 1954. A four point bending setup is proposed and designed to analyze the piezoresistance effect in p-type silicon. This setup is used to apply uniform and uniaxial stress along the crystal direction. The main aim of this work is to ...

Cantilever vibration in fluid environment is probably one of the most common Fluid Structure Interaction problems in the field of Micro/Nano Electro Mechanical Systems. Usually the effect of fluid on cantilever oscillation is characterized in terms of mode resonance frequencies and quality factors (Qs). In this work a new approach to the above FSI problem is proposed: modes Q factors and ...
