Electrical stimulation of the brain involves the application of currents delivered through scalp electrodes to modulate brain activity, known as Transcranial Current Stimulation (TCS). A critical factor for TCS efficacy and safety is the “spatial focality” of induced neuronal modulation. ... 詳細を見る
Convective instability in a thin liquid layer is observed in many technical systems [1] and is of interest to the self-organization theory. To date, however, only simple problems with the convection between flat plates are well studied [2]. In real systems and devices, convective flows ... 詳細を見る
Additive Manufacturing is revolutionizing the industrial sector for complex and individualized metallic components. The most limiting factor of the widely established laser beam melting technology is the scan velocity due to inertia of the mirrors [1]. In electron beam melting (EBM), ... 詳細を見る
The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. ... 詳細を見る
The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... 詳細を見る
Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying ... 詳細を見る
本文基于热传导方程，采用COMSOL有限元模拟软件中的固体传热接口研究TC4钛合金在进行飞秒激光表面扫描过程中的温度场变化。模拟采用控制变量法，通过改变不同的加工参数（脉冲能量、重复频率、扫描速度等）模拟飞秒激光加工对TC4钛合金表面瞬时最高温度的变化的影响。模拟结果表明，在多脉冲飞秒激光照射下，单个脉冲能量越高，热积累的平衡温度越高；脉冲重复频率越高，表面接受总能量越多，热积累平衡温度越高；扫描速度可以影响热积累的平衡，改善材料因表面最高温度过高而发生的氧化或熔化等不良现象。模型的模拟结果与经过验证的基于Matlab软件的数值模型的模拟实验结果相近 ... 詳細を見る
Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics. Focused laser beams, optical tweezers, may be used to manipulate such NPs. However, experimental studies showed that there is a discrepancy between their predicted and observed behavior. ... 詳細を見る
The ongoing trend towards miniaturization, higher integration as well as cost efficiency will make it necessary to investigate a new assembly method for micro components. In this paper, a novel method of fluidic-based micro assembly is presented. A self-assembly effect which is caused by ... 詳細を見る
Since the advent of Terhertz(THz) technology, improving the THz emission power has been one of the major research goal. One of the methods to increase the THz emission power is to increase the coupling of excitation laser light to the dielectric substrate.The field of nano-plasmonics ... 詳細を見る
