In the past decades, equilateral polygonal microcavity lasers with whispering-gallery modes (WGMs) have attracted great attentions due to their potential application in photonic-integrated circuits. Compared to the perfect microdisk without deformation, the polygonal microcavities such ... 詳細を見る
In this paper, all optical microring resonator based on Lithium Niobate on Insulator (LNOI) has been proposed. LNOI has high refractive index contrast and also show better electro-optic & acousto-optic effects. The optical ring resonator resonates when the optical path-length of the ... 詳細を見る
The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... 詳細を見る
Core-shell type plasmonic nanoresonators have been optimized to maximize the fluorescence rate of coupled dipolar emitters, namely SiV color centers in diamond. The RF module of the COMSOL Multiphysics® software was applied to extract the optical response and to analyze the near-field ... 詳細を見る
It is well-known that metal nanoparticles (NPs) excited at the plasmon frequency not only exhibit peculiar optical properties (e.g., a peak in the extinction spectrum, an enhanced electromagnetic near-filed) but also heat up [1]. This phenomenon is highly investigated for medical ... 詳細を見る
A) Abstract: There has been a spectacular growth in the field of wireless communication in recent years. Current trends in mobile wireless communications demand technologies that allow a single device or system to operate across multiple frequency bands and protocols. This cannot be ... 詳細を見る
Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... 詳細を見る
Passive, one-way valves, also known as check valves, while common at the macro scale, are an essential microfluidic feature that facilitate flow rectification. These structures are also commonly used in reciprocating micropump configurations to control flow. Their operation can be ... 詳細を見る
In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass ... 詳細を見る
钴基高温合金，因其优异的高温综合性能而被广泛应用于航空发动机制造等领域，激光增材制造是制造几何形状复杂的高温合金零件的有效途径。目前，高温合金增材制造中，缺陷与组织成分的控制是关键的技术瓶颈，而这两方面的问题都与熔池中的热质传输过程密切相关，因此我们将研究的方向着眼于揭示熔池流动背后复杂的物理现象。本研究基于 COMSOL 多物理场耦合，应用 ht、tpfmm、tcs 接口，提出了适用于高温合金多组分热质传输的数值模型，研究了温度梯度G以及凝固速率R对界面围观凝固组织的影响以及钴基合金中主要成分 Fe、C、Co、Cr 的传质特性以及成分分布 ... 詳細を見る
