Surface plasmon resonance (SPR) sensors proved themselves as a promising device for many kinds of applications such as optical biosensing, binding constant determinationor nanofilm thickness measurements. Here we simulate using COMSOL Multiphysics® the light-polaritons coupling for the ... En savoir plus

Partial differential equations (PDEs) govern many phenomena in nature. Solving optimization problems which comprises the solution of large number of PDEs, is expensive concerning time and memory. Therefore, to reduce the solution cost, original problem is transformed to a corresponding ... En savoir plus

It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... En savoir plus

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... En savoir plus

In the last decade, the surface plasmon resonance (SPR) has become a very sensitive technique for real-time detection in many application areas. Considering the fiber optic concept and the important needs for analyzing biomolecular reactions through automated and miniaturized components, ... En savoir plus

Nanoantennas have been successfully employed in a wide set of applications. We show the possibility to expand usual nanoantenna functionalities in the THz domain with a gold dipole nanoantenna. We considered an array of aligned planar gold nanoantennas over a silicon substrate. The high ... En savoir plus

Hydrogen Embrittlement (HE) is one of the mechanisms responsible for premature failure of structures. In the context of environmental sustainability, it is compelling to improve or conceive new processes and/or new materials capable of reducing fracture induced by HE. We analyzed the ...

The nematode Caenorhabditis elegans is a widely adopted model organism for studying various neurobiological processes at the molecular and cellular level in vivo. With a small, flexible, and continuously moving body, the manipulation of C.elegans becomes a challenging task. A lab-on-a ... En savoir plus

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus

The specular and diffuse reflection properties of sunlight at the rear surface of silicon solar cells with various degrees of roughness are computed by solving the Maxwell and material equations in two dimensions, using the COMSOL RF Module. The model is tested on planar Si/SiO2/air ... En savoir plus
