摘要:

对由不同媒质所组成的电磁场场域,当分界面上场的散度源和旋度源不为零时,场量将在分界面两侧发生突变,通常使用的单一媒质区域中的斯托克斯公式不再适用这种情况.推广了单一媒质中的斯托克斯公式,得到了适用于多媒质区域的多曲面斯托克斯公式.对于由不同媒质所组成的电磁场场域,利用所推广的多曲面斯托克斯公式,给出了电磁场边界条件的一种新的推导方法.所推导的公式对于由多种媒质组成的矢量场有广泛应用.

Abstract:

For the electromagnetic field field composed of different media, when the divergence source and curl source of the field on the sub-interface are not zero, the field quantity will change on both sides of the sub-interface, and the Stokes formula in the commonly used single medium region is no longer applicable. The Stokes formula in a single medium is generalized, and the multi-curved Stokes formula applicable to the multi-media region is obtained. For the electromagnetic field field composed of different media, a new derivation method for the boundary conditions of electromagnetic field is given by using the generalized multi-surface Stokes formula. The derived formula has wide applications for vector fields composed of multiple media.
