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 ... 詳細を見る

Ultrafast optical generation of pseudosurface acoustic waves is investigated in hypersonic surface phononic crystals. The thermomechanics is modeled from first-principles to follow the initial impulsive heat-driven displacement in the time domain. Spectral decomposition of the ... 詳細を見る

A finite element model is employed to describe the electric potential distribution and electroosmotic flow field inside a wavy cylindrical channel. The model uses coupled Laplace and Poisson-Boltzmann to evaluate the electric potential distribution inside the channel. It also contains ... 詳細を見る

In this paper the heat transfer module in COMSOL is utilized to simulate internal heating of an Avalanche Photodiode due to light-induced current through a resistivity that depends on charge carrier concentrations in the device. Initial tests are done by modeling the heating process on a ... 詳細を見る

Established joining techniques like welding, soldering or brazing typically are characterized by a large amount of heat load of the components. Especially in the case of heat sensitive structures like MEMS this often results in stress induced deformation and degradation or even damaging ... 詳細を見る

Gallium nitride (GaN) and its related nitride alloys with special physical properties are in technical areas of high interest. The growing of gallium nitride boules on non-native sapphire or silicon carbide requires complicated mechanisms of defect reduction in the lattice structure. ... 詳細を見る

Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... 詳細を見る

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is ... 詳細を見る

Flexible electronics are temporarily affixed to a rigid carrier such as glass or silicon prior to device fabrication to facilitate robotic handling of the device, but also to allow optical lithography to stay within overlay design registration budget; without the rigid carrier, a ... 詳細を見る

Anil Prabhakar joined the faculty at IIT-Madras in 2002, after 5 years of post-doctoral experience in the hard disk drive industry. His current research interests include photonics, spintronics, nonlinear dynamics and alternative and augmentative communication. As a member of the Optics ... 詳細を見る
