Metasurface design often relies on labor-intensive geometric tuning and repeated full-wave simulations, making the exploration of sample spaces labor-intensive. In this article, we present an end-to-end automated framework for the inverse design of metasurface absorbers and circular ... Mehr lesen

电刀是外科手术重要器械，依靠电极-生物组织局部回路完成组织切割与凝血，热损伤控制是其临床应用关键。为研究双极电刀动态切割生物组织的电热作用机制，基于COMSOL Multiphysics构建电热多物理场耦合有限元模型，结合电流守恒方程与Pennes生物传热方程实现电场-传热双向耦合，引入移动网格技术复现电刀动态切割过程，求解组织内部电场与温度场的演化特征。结果显示，电场高度集中于双极电极附近，高温区域随电极运动沿切割轨迹同步迁移；切割移动速率显著影响组织峰值温度与侧向热扩散范围，低速切割易引发更大侧向热损伤，高速切割可获得较窄切口，但存在切割不充分的风险 ... Mehr lesen

Interfacial dipoles are commonly represented in semiconductor device models by effective work-function or energy-level shifts. [1,2] However, whether such a reduced description remains equivalent to a spatially resolved dipole under device operating conditions is not obvious. Here, we ... Mehr lesen

Optical metasurfaces, composed of subwavelength unit cells, are two-dimensional artificial platforms that enable exceptional electromagnetic wave manipulation unattainable in natural materials, playing pivotal roles in enhancing light-matter interactions [1]. Resonance, ubiquitous in ... Mehr lesen

Unidirectional guided resonances (UGRs) enable static unidirectional radiation of eigenstates and have been widely studied. Exceptional points (EPs) in non-Hermitian open systems provide a unique perspective for exploring UGRs. However, existing studies mainly focus on the topological ... Mehr lesen

This research reveals that expansion flow generates nanosheet alignment, whereas subsequent plug flow suppresses shear-induced reorientation and preserves the vertically aligned structure. COMSOL Multiphysics was employed to investigate the flow behavior of non-Newtonian graphene oxide ... Mehr lesen

Background Microwave ablation (MWA) induces non-uniform temperature changes within tissue while simultaneously altering its thermal and electrical properties during the heating process. These changes can potentially be reflected through bioimpedance measurements, thereby providing an ... Mehr lesen

计算建模可用于构建随机裂缝网络以表征裂缝性储层，并预测其流动响应特征。针对传统随机裂缝网络模型构建时泛化性差、对流动描述不确定性强且易失真的缺点，考虑裂缝几何形态与拓扑连通结构的协同作用，提出了几何-拓扑参数约束的随机裂缝网络模型建模方法，在验证约束生成模型渗流特性可靠的基础上，通过不确定性量化分析识别了不同几何参数、拓扑参数对裂缝网络连通效率的贡献，并提出主控因素驱动的裂缝网络模型建模实用化途径。研究成果为工程尺度裂缝性储层的快速建模提供了兼顾精度与效率的实用化方案。 Mehr lesen
