在本文中,我们研究的时谐麦克斯韦问题的符号变化的介电常数和/或磁导率,设置在一个域的103。我们使用T-矫顽磁力方法证明,具有Dirichlet和Neumann边界条件的两个正则相关标量问题的适定性意味着麦克斯韦问题的适定性。这使我们能够给出简单而尖锐的标准,在标量情况下的研究中获得的,以确保麦克斯韦传输问题之间的经典介电材料和负超材料是适定的。
In this paper, we study the time-harmonic Maxwell problem with sign-changing permittivity and/or permeability, set in a domain of ℝ3. We prove, using the T-coercivity approach, that the well-posedness of the two canonically associated scalar problems, with Dirichlet and Neumann boundary conditions, implies the well-posedness of the Maxwell problem. This allows us to give simple and sharp criteria, obtained in the study of the scalar cases, to ensure that the Maxwell transmission problem between a classical dielectric material and a negative metamaterial is well-posed.
