    圆形平板电容器的磁场与位移电流的磁效应
  • On the similarties and differences between the displacement current and the electric current on exciting the magnetic field
    位移电流和传导电流在激发磁场方面的异同
  • After the discussion of the numerical simulation method based on the fdtd method and the pml technique , the motions of the charges and the electrical field lines were first employed to describe the radiation procedures of the pulse electromagnetic waves . then the causes of how the charges are accelerated and how the motion status of the charges are maintained were further studied from the angle of interaction of charge and field . after these analyses , it was pointed out that the pulse radiation is due to the suddenly occurred time - varying electrical field ( displacement current ) in the open space . this view was further evidenced by two examples : one is the partly resistance loaded antenna , the other is the partly curved antenna . the radiation procedures of the pulse electromagnetic waves of many different situations were simulated throughout this paper with the contours and waveforms of electric field given . these figures are very helpful to the understanding of the radiation mechanism of the pulse electromagnetic waves
    在讨论了基于时域有限差分法和完全匹配层技术的数值模拟方法之后,首先从运动电荷和电力线的角度直观地描述了脉冲电磁波的辐射过程,然后进一步从场与电荷相互作用的角度分析了天线上电荷是如何被加速以及如何维持其运动状态的,指出了开放空间中突然出现的时变电场(位移电流)是脉冲电磁波辐射的根本原因.文中还对局部电阻加载的天线和局部弯曲的天线进行了研究,以进一步说明上述观点.对多种情况下的脉冲辐射过程进行了数值模拟,并给出了电场的等高线和空间波形图,这些图形对理解脉冲电磁波的辐射机理非常有益

百科解释

In electromagnetism, displacement current is a quantity appearing in Maxwell's equations that is defined in terms of the rate of change of electric displacement field. Displacement current has the units of electric current density, and it has an associated magnetic field just as actual currents do.
