本文的主题是对电磁现象的所有可能的传输问题进行回顾。特别地,我们通过电导率接近于零或无穷大的形式极限来研究理想介质和理想导体的情况,并讨论了所涉及的未知数的期望规律性。最后,我们为每个考虑的问题建立了等价的变分公式。
The subject of this article is a review of all possible transmission problems for electromagnetic phenomena. In particular, we study the case of a perfect dielectric and a perfect conductor via a (formal) limit with conductivity approaching zero or infinity and discuss the expected regularity of the involved unknowns. Finally, we formulate equivalent variational formulations for each considered problem.
