本报告首先回顾传统低频涡流场的两种计算格式,指出有限元编程实现过程中的基函数选择以及需要注意的难点问题。第二部分针对静磁场问题,通过引入规范条件提出了一种基于矢量磁位和磁场强度的新型的对偶格式,该方法通过巧妙构造基于矢量磁位和磁场强度的计算格式,整体矩阵完全一致并且可以给出系统电感参数的上下界,在实际参数提取中有很好的应用前景。在第三部分,由于传统低频涡流场近似不能有效考虑分布电容效应,而传统高频...
We are very pleased to invite you to participate in Compumag 2017 to be held in Daejeon from June 18 ~ 22, 2017.
The problem of the electromagnetic field created by a thin, straight conductor of infinite length carrying a forward traveling-wave current with a complex propagation constant g above a homogeneous an...
Since the end of 2007 a new electromagnetic field monitoring station has been in operation in Central Italy in the area of a village called Duronia. The station was created in the framework of the MEM...
For the di raction of an incident plane electromagnetic wave by a slotted metallic lm, the previous analytical calculation for a single slot [Technical Phys. 50, 1076 (2005)] is generalized into a mo...
Electromagnetic properties of quark-like particles are examined in a classical field model involving extended dual electromagnetic fields. These can have fractional charges and a confining potential t...
We consider effects of the fields of strong electromagnetic waves on various characteris- tics of quantum processes.
The paper elaborates a dynamic scheme which accounts for the evolution of nematic liquid crystals. The liquid crystal is allowed to be compressible and subject to the action of mechanical and electrom...
During the last decade, several studies have focused on the adverse effects on health caused by exposure to electromagnetic fields (EMF). Some epidemiological studies of workers exposed to EMF have sh...
To evaluate the potential teratogenic effects of electromagnetic fields on the skeletal systems of rat fetuses. MATERIAL AND METHODS: Twenty-five pregnant rats, which had been exposed to electromagnet...
Although bone healing around titanium implants has already been evaluated, the effect of pulsed electromagnetic fields (PEMF) during the period of bone maturation around titanium dental implants ha...
In this study, a method of the metallisation of polypropylene (PP) nonwovens is presented. The influenceofpowerdissipatedinthetargetontheefficiencyofscreeninga flatelectromagnetic wave is discussed. ...
Biological Effects and Safety of Exposures to Radiofrequency Electromagnetic Fields from Mobile Communications.
Results obtained in research on the effects of EMF (electromagnetic field) and EMR (electromagnetic radiation) on seeds and seedlings show that it is still impossible to draw coherent conclusions. The...
The impact of electromagnetic fields of the power of 1800 Am-1 (=H), 1000 Am-1 (=H), 800 Am-1 (~H), 1500 Am-1 (~H), 200 Am-1 (~H) on the morphological and physiological parameters of tomato plants wh...
