Voltage sensors are increasingly used for monitoring and load flow distribution. These sensors are safer, lighter in weight and lower in cost as compared to the conventional voltage transformers. The principal component of these sensors is high voltage resistors. The resistors have a ... En savoir plus

1.Introduction Transparent conductive oxides (TCOs) operating near their epsilon-near-zero (ENZ) point have recently been shown to exhibit strong and ultrafast intraband optical absorption processes, whose excitation results in a variation of the effective mass and electrical conductance ...

The utility company may shut off power in the overhead transmission or distribution lines as a preventative measure against wildfire risks and to ensure public safety. However, the de-energized transmission lines can still carry energy due to induced voltage from the electric- and ... En savoir plus

Impedance spectroscopy is an established sensing methodology used in microfluidic flow cytometry systems to electrically measure cell characteristics. The fluid transport method used in most flow cytometers is continuous flow driven by external syringe or pressure regulated pumps. An on ... En savoir plus

Abstract for COMSOL Conference With the world continuously scaling MOSFETs into smaller submicron dimensions, subthreshold current and threshold voltage control are important challenges to ensure optimal device performance. This study explores the effects of halo implants on simulated ... En savoir plus

We narrow the consideration to HV cylindrical parts, typically with axial leads located on the opposite sides. They are tens of millimeters long, so at moderate frequencies of up to 10MHz they may be analyzed as lumped elements (not as transmission lines), although in some cases they may ... En savoir plus

Steel tubes are widely used in industries. In order to ensure the safety and reliability of industrial processes, electromagnetic acoustic transducers (EMATs) based guided wave technology has been developed for inspecting stainless steel tubes regularly. Theoretical models and finite ... En savoir plus

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential ... En savoir plus

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... En savoir plus

We used COMSOL Multiphysics® software to calculate the mode distribution by numerically solving the wave equation in the fiber. We consider the transmission from the fiber 1 to the fiber 2. In the first case, the transmission was calculated as function of the wavelength of the propagated ... En savoir plus
