Vacuum window is required in the millimeter wave transmission line in ITER*. It is to be designed to minimize the microwave reflection while keeping a robust and safe approach to meet the requirements. We have studied transmission characteristics of various dielectric materials over D ... 詳細を見る
In this conference we have brought together a community that is scientifically diverse in an event that allows for inspiring contacts about the use of COMSOL Multiphysics. It is an event to connect with the Spanish and Portuguese COMSOL Multiphysics users and participate in training ... 詳細を見る
Terahertz radiation (THz) is defined to have frequencies from 0.1-10 THz (1 THz=1e12 Hz). This radiation lies between microwave and infrared radiations in the electromagnetic spectrum. Metamaterials are designed periodic materials that show exotic properties to light and sound. ... 詳細を見る
Probing ultrafast processes over subpicosecond and picosecond time scales provides fundamental insight into the nature of materials. We have experimentally demonstrated terahertz (THz)-pulse-induced tunneling in a scanning tunneling microscope (THz-STM) to image surfaces with ... 詳細を見る
In Mexico there is a decline in the production of oil deposits due to the lack of effective treatment of oil emulsions, which generate a problem in the reinjection of emulsified water, transport of oil with high water content and corrosion in the oil refineries. Through the simulation ... 詳細を見る
Engineering design has long been dominated by orthogonal Cartesian principles. Nature inspired equation based mathematical surfaces are under renewed interest due to their innovative design potential and practical viability by 3D printing. In this paper, the parametric surface ... 詳細を見る
复合型电磁轨道发射装置是轨道型电磁发射器研究的一个重要方向，复合型轨道是对轨道的内表面添加保护层，由于电磁轨道在发射时存在复杂的热量变换，轨道表面材料在吸收这些热量之后会发生脱落、气化甚至是电离等现象。为减弱在发射过程中的烧蚀现象，在轨道的表面添加保护层，使轨道内表面材料具有强的耐热性能，并且强度、韧性较好。运用 COMSOL Multiphysics® 软件仿真模拟复合轨道在发射过程中的温度、电流、应力和应变的变化。 詳細を見る
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... 詳細を見る
The Levitron offers an interesting demonstration of natural magnetic levitation using permanent magnets. It is composed by a small magnetized top and a circular magnetized base with a hole on its center. The top is placed in an area where magnetic field configuration and gyroscopic ... 詳細を見る
Cogging torque in permanent magnet motors and generators is characterized by a torque ripple. These torque fluctuations cause vibrations, noise and speed fluctuations. This paper presents finite element (FE) analyses results that show a previously unaddressed low frequency modulation of ... 詳細を見る
