Due to the inseparability of the wave equation, numerical methods are needed to develop an accurate electromagnetic model for various axisymmetric resonators such as micro-discs and micro-toroids. Our purpose is the implementation of a perfectly matched layer to determine the quality ... Read More
We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered ... Read More
Designing a Radio Frequency (RF) birdcage coil used in Magnetic Resonance Imaging (MRI) at high frequencies where the wavelength is comparable with the coil dimensions is a challenging task. Before construction of the coil, not only calculating the capacitance value which is necessary ... Read More
Diabetes is a chronic noncommunicable disease which lays a heavy burden on many impoverished communities globally. The ability to monitor and manage the disease is one key component to lessening its impact. 3D printing (3DP) offers an economical manufacturing method to produce medical ... Read More
Laser surface texturing has emerged as a promising texturing technique due to properties such as excellent repeatability, non-contact process, the ability to achieve small-size features and high-quality finishing.

电磁辐射对燃油危害是加油站、炼油厂、油气基地等大型设施禁用手机和其他无线通讯设备的重要原因。不同于静电对燃油蒸气的危害，本文的研究重点在于分析不同频率下的射频放电击穿特性。基于射频等离子体鞘层模型，通过多物理场仿真，分析了12M~300MHz频率下的氩气射频放电过程。仿真结果表明，当激励频率大于雪崩击穿临界频率时，两侧极板附近会形成随激励周期变化的鞘层区，中心区域为准电中性的等离子体区。同时，当激励频率远小于等离子体频率时，鞘层会促进极板附近的γ电离过程；随着频率增大，鞘层特性会逐渐退化，而中心区域的α电离过程会增强。此外，放电特性曲线表明，频率越高，板间放电电压越小 ...
