Wireless sensor network has been extensively applied in a wide variety of areas such as defense, agriculture, transportation, etc. The major challenge in those networks is the finite energy of the sensor node which is by and large engaged in transmitting and receiving data. It is known that substantial amount of energy is consumed in transmitter portion. The constituent unit of the transmitter i ...

微波辅助生物柴油生产越来越受到了人们的关注，但是，微波的不均匀加热也影响了微波辅助生物柴油的大规模生产。研究表明，连续流微波加热器可以有效地解决微波辅助生物柴油的批量生产问题，螺旋推进器也可以改善加热均匀性，于是仿真带有螺旋推进器的连续流微波加热器的生物柴油生产过程，有利于优化连续流微波加热器的设计，对提高微波辅助生物柴油生产效率有重要的意义。 本文使用了电磁场、旋转机械流、流体传热和化学反应接口。电磁场中的介电系数是关于温度和物质浓度的函数，流体的热参量由流体各组分的质量比等效所得。计算采用步进求解的方法，先在频域求解电磁场，所得的耗散功率代入流体传热，再将求解得到的温度和浓度用于更新介电系数，如此类推直至计算时间结束。 图1为有无螺旋推进器的连续流微波加热器的纵截面温度分布图，可见由于螺旋推进器的搅拌作用，流体的温度均匀性得到了很好的提高 ...

Liquid-crystal elastomers (LCEs)  have attracted a great attention in recent years due to their high potential in a wide range of applications, from microfluidics components  to artificial muscles . The photo-mechanical response of LCEs is due to their constitutive photo-sensitive molecules, which change shape when absorbing part of the incident light. These microscopic deformations can ...

The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase of the plasma frequency reduces the electromagnetic wavelength. Therefore, the electric field distribution is ...

By using a combination of top-down and bottom-up strategies (see Fig. 1), rolled-up optical microcavities have gained considerable attention owing to their excellent customizability . For example, the resonant spectrum of a rolled-up optical microcavity is well defined by simply tailoring the rolling length before it rolls , as shown in Fig. 2. In order to have a good visualization for the ...

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has necessitated that cost-effective preventive measures, which have an immediate impact on the burden at population ...

Surface plasmon resonance in metallic nanoparticles is highly and shape dependent, which enables varius applications in photovoltaics, photonics, sensing and even medicine. Particularly we observe redshift in plasmon resonance with increasing nanoparticle size. We investigate nanoparticle size influence on plasmon resonance within theoretical and numerical approach and compare results with ...

Detecting light emitted by fluorescent molecules with resolution down to single photon is an important problem in various fields of sciences and applications, such as solid-state physics, quantum information processing and medicine. The detection probability can be improved via enhancement of excitation and emission. Enhancement both of these processes can be reached by localized surface plasmon ...

近年来，三维系统级封装技术逐渐成为人们的关注焦点，是下一代集成电路封装设计最有发展潜力的实现方案。然而，热管理是系统级封装技术需解决的关键问题。图1是典型的系统级封装结构，包含堆叠芯片、硅通孔、封装基板、热界面材料以及多层凸点结构。若对该结构的所有细节进行建模，将会消耗巨大的计算资源，导致分析效率非常低下。因此，本论文将封装中的硅通孔层以及凸点层等复杂结构进行等效处理，提取它们在水平和垂直方向上的等效热导率以及等效比热容、等效密度等参数。例如，在建模过程中，采用 COMSOL Multiphysics® 传热模块对硅通孔层的水平方向等效热导率进行提取，边界设置如图2所示，通过仿真得到的热源端温度来推导等效热导率。类似地，垂直方向的等效热导率提取如图3所示。经过上述处理，可将封装中的硅通孔层以及凸点层等复杂结构等效为介质均匀的材料，然后再采用 COMSOL 进行整体封装结构的热仿真 ...
