In this study, a computational model is developed and solved using COMSOL Multiphysics software to estimate the lesion size during saline-infused RFA. Transport of saline is set up by modifying the Poisson equation and the convection-diffusion equation  under the Mathematics module. Heating during RFA is set up based on the Joule heating module. To describe the lesion size, the two-state cell ...

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 ...

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate.

This work presents an alternative method for curing cork stoppers based on microwave radiation, which is energetically more efficient, where it is possible to accelerate the reaction rate and therefore reduce the cure time comparatively with conventional curing methods. The microwave energy is directly introduced in the volume of the dielectric material and as a consequence, the quality of the ...

Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of mass, momentum and energy transport. Three phases are considered in the system: solid (skeleton), liquid (water) ...

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 Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction between the stator and the slider. A LiNbO3 piezoelectric substrate is used as a stator where comb structured Al ...

Metamaterial-based absorbers play a significant role in applications ranging from energy harvesting and thermal emitters to sensors and imaging devices. The middle dielectric layer of conventional metamaterial absorbers has always been solid. Researchers could not detect the near field distribution in this layer or utilize it effectively. Here, we use anisotropic liquid crystal as the dielectric ...

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 ...
