A 3D thermo-mechanical simulation was developed using COMSOL Multiphysics software in order to predict distortion of a welded dissimilar titanium alloys structure. An angular distortion and a longitudinal shrinkage are predicted in agreement with those obtained experimentally. 詳細を見る

设计了一种新型的介质激光波荡器。该设计的核心是一个周期性的介质结构，其两侧形成一个真空通道。通过引入两束特定波长的相向传播的平面激光波，在该真空通道内激励并产生一个相位同步的周期性电磁场。主要难点在于如何设计介质结构，使其在激光作用下，能够最大化提供偏转作用的横向电场Ey，同时必须将其他方向的场分量（如纵向场 Ez和加速场 Ex）对电子束的影响降至最低。 利用 COMSOL 求解了在两束相向传播的激光照射下，该周期性结构内部真空通道中的电磁场分布。通过仿真，验证即是否能成功在通道中心产生期望的周期性横向偏转电场，直观地展示电场沿不同方向的变化规律，从而评估波荡器的性能 ... 詳細を見る

本文提出了一种新颖的介电激光加速器（DLA）结构，该结构利用三角梯度介电介质来增强逆切伦科夫效应（Inverse Cherenkov Effect, ICE），从而实现高梯度加速。逆切伦科夫效应是带电粒子从外部激光场中持续获取能量的过程，这在传统切伦科夫效应中是相反的，即粒子发射辐射。通过在介质中精确控制激光束的传播，可以产生一个与粒子速度同步的纵向电场分量，实现连续的净能量增益。为了验证这一概念并分析其性能，我们使用 COMSOL Multiphysics 进行了系统的仿真研究。仿真模型由一个位于自由空间域中的介电结构组成。我们应用散射边界条件（SBC ... 詳細を見る

In all implantable medical devices, one main challenge is to assure no water penetrates in the electronic part of the system. To be able to transmit the electronic information from the inside of the device to the lead without any water infiltration, we used a complex part called feed ... 詳細を見る

Laser immunotherapy (LIT) was developed to treat late-stage, metastatic cancers through local laser irradiation and immunological stimulation. In ILIT, the photothermal effect induces immune responses by destroying and interrupting tumor cells through temperature elevation in target ... 詳細を見る

Aerostatic bearings are widely employed in high-precision systems, particularly in micromachining applications. Their contactless operation eliminates mechanical friction, enabling highly accurate and repeatable motion. This makes them especially valuable in metrology and advanced ... 詳細を見る

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in ... 詳細を見る

A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88 ... 詳細を見る
