双周期结构电磁散射的唯一性

On Uniqueness in Electromagnetic Scattering from Biperiodic Structures

Armin Lechleiter, Dinh-Liem Nguyen

摘要:

考虑三维理想导电平板上双周期介质结构对时谐电磁波的散射。在适当的索伯列夫空间中,利用Fredholm变分框架证明了该问题解的存在性.在本文中,我们得到了一个Rellich恒等式的解决方案,这个变分问题在适当的光滑条件下的材料参数。在额外的非捕获假设的材料参数,这个身份使我们能够建立所有波数的解决方案的唯一性。

英文摘要:

Consider time-harmonic electromagnetic wave scattering from a biperiodic dielectric structure mounted on a perfectly conducting plate in three dimensions. Given that uniqueness of solution holds, existence of solution follows from a well-known Fredholm framework for the variational formulation of the problem in a suitable Sobolev space. In this paper, we derive a Rellich identity for a solution to this variational problem under suitable smoothness conditions on the material parameter. Under additional non-trapping assumptions on the material parameter, this identity allows us to establish uniqueness of solution for all wave numbers.
