摘要
由静态场的泊松方程求出任意形状导体空腔内的电位和场强分布,说明即使导体空腔表面的电荷分布不均匀,但空腔内部的电位仍然处处相等,整个导体是等位体,场强分布为零,与导体空腔形状无关.这一结论在分析静电屏蔽及TEM波在空芯金属波导管中的传播有一定的意义.
The electric potential and electric-field intensity distribution in conductor cavities of random shapes can be get through the Poisson's equation of the electrostatic field.The results explain,even if the distribution of electric charge in the conductor cavity's surface is non-uniform,that the electric potential in the cavity is the same here and there,the whole conductor is equivalent-potential,and the electric-field intensity distribution is zero,which is no relation to the shapes of conductor cavities.The conclusion is very significance in analyzing the electrostatic shielding,electromagnetic shielding or the transmission of TEM wave in the wave-guide slot of hollow metal.
