In this paper, a resonant coupling wireless power transmission system whose resonator using single-layer helical coils is designed. Based on analysis of equivalent circuit, the efficiency and optimal transmission distance are obtained, and its correctness is verified by experiment. The resonant frequency and electromagnetic field distribution of system are obtained through high frequency finite element...
The application of external magnetic field in the electromagnetically induced acoustic emission technique (EMAE) can enhance the ability of detecting the defects and reduce the stimulation current flow in the coil, due to the even bigger deformations generated by the enhanced Lorentz Force at the defects. In this paper, the finite element model of EMAE including an external magnetic field has been...
Magnetic stimulation has become a very topical research area in bioelectromagnetics studies. One of the major problems in understanding the observed changes in biological systems resulting from exposures to magnetic fields is the relationship of biological changes to physical processes. It is well known that acupuncture has many varied physiologic effects on the functional systems of human subjects...
The paper aims to quantitatively investigate the electromagnetic behaviors of silicon steel lamination used for magnetic shielding in large transformers. 3-D eddy current codes based on Ar-V-Ar method are developed. The non-linearity, hysteresis and anisotropy of the material are taken into account when the electromagnetic field is analyzed. A practical way is advised to model the lamination material,...
In this paper, the finite element analysis of a recently developed electromagnetic acoustic emission (EMAE) which can be used for damage assessment of thin walled conducting structures has been reported. Due to the local high-intensity stress field generated by the electro-magnetically induced high-density current pulse, EMAE can locate small flaws or cracks in thin-walled structures non-destructively...
