This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, ... Mehr lesen
Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... Mehr lesen
There is an increasing demand for aerosol devices from E-cigarettes to drug delivery devices with precise dosage. [1][2] The aim of this article is to investigate a Poly-Si micro heater in a vapor generator device. In order to calculate the amount of vapor production, temperature ... Mehr lesen
Abstract. A Laser Focusing system (LFS) focuses a single laser beam (single Channel) or multiple laser beams (multi - channel) onto a surface (Specimen). The general motive of a LFS is to focus a train of brief pulses or a continuous beam of light onto a Specimen which heats up its ... Mehr lesen
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 ... Mehr lesen
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 ...

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 ... Mehr lesen
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. The work described here is part of the H2020 research program called SHARK ... Mehr lesen
Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the ... Mehr lesen
Perfectly matched layers (PML) are an efficient alternative for emulating the Sommerfeld radiation condition in the numerical solution of wave radiation and scattering problems. The key ingredient of the PML formulation is the complex scaling function, which controls the anisotropic ... Mehr lesen
