Because of to their versatile energy choice alternatives, immovable elements, and opportunity for effective generation, thermophotovoltaic techniques have a vast range achievable applications. For illustration, these devices could help us offer convenient energy. Nevertheless, first enhance the performance thermo-photovoltaic cell unit along with decrease system costs temperatures. To achieve s...

Electrical models for microelectrode-cell interfaces are essential to match electrical simulations to real biosystems performance and correctly to decode the results obtained experimentally. The accurate response simulation of a microelectrode sensor to changes in the cell-electrode system, such as cell growth, enables the optimum microelectrode design process. We report the use of COMSOL quasi...

A V-band CMOS-MEMS switchable phase shifter based on reflection-type topology is presented in this work. Phase shifter is simulated by using CMOS process. Three discrete phase states are achieved at 65GHz by using Bi-directional fishbone actuators. The measured insertion is very less and the return loss is also better than 14 dB over the 55-65GHz frequency range. It demonstrates a great potenti...

The aim of this paper is to build a dynamic thermal model of power LED for simulation environment COMSOL. The dynamic thermal model was based on technical and application manufacturer's data of power light emitting diode. In this way the assembled electrical and thermal model of power LED was simulated in a dynamic process of load within Comsol simulation program. The simulation results have be...

The aim of this paper is to introduce a method for creating a homogenous substitute material for composite materials using optimisation algorithms. Composite materials are modern construction materials used, for example, in aircraft construction. However, numerical modelling of these materials is, due to its multi-layer structure, very difficult to compute. This multi-layer structure and loss m...

According to the American Stroke Association, stroke is the No. 4 cause of death and the leading cause for adult disability in the United States. Some of the complications of stroke are a direct result of inflammatory responses in the brain. Studies have shown that many neuropeptides display neuroprotective behavior by ameliorating neuronal damage caused by such a response. Although its mechani...

Whispering-gallery mode (WGM) resonators are promising elements for future photonic devices, as they combine ultra-high quality factor with small size and mode volume. Many device schemes, such as electro-optic modulators [4, 7], receivers [6] and optoelectronic generators [8] and optical combs [2], has been suggested. They also found applications in science like optomechanics [3] and quantum c...

This paper presents a triangular-lattice photonic crystal fiber for analysis of nearly zero ultra-flattened dispersion like 0.96 -0.86 ps/nm/km with very low confinement loss less than 10 db/km, moderate effective area, lower splice loss & nonlinear coefficient property of photonic crystal fibers. A five-ringed photonic crystal fiber have be designed using Comsol 4.2 with the finite element met...

We report the use of Heat transfer Module of COMSOL multiphysics and a technique based on Infrared Photothermal Radiometry to study the heat transfer of a homogeneous and isotropic solid material excited by a periodic laser beam on the front side of the sample, and an infrared detector on the rear side in order to obtain the evolution of the temperature difference with the exposure time. Also, ...
