我们分析了以下具体的隐蔽性问题:隐蔽性区域由一个与占据外部背景空间的介质相同的均匀介质球体构成;这个球体被一个占据球壳的隐形介质包围,该介质由参数仅取决于径向变量r的材料组成。对于这个非常特殊的情况,我们表明,确定表征隐形介质的三个函数,即径向质量密度、切向质量密度和可压缩性的问题,可以简化为求解一个定义良好的Schrödinger方程的逆问题。特别地,通过黎曼-希尔伯特问题的解,介绍了用径向质量密度来确定上述三个函数中的两个的具体程序。
We analyze the following particular cloaking problem: the cloaked region consists of a sphere of a homogeneous medium which is identical with the medium occupying the exterior background space; this sphere is surrounded by a cloaking medium occupying a spherical shell and consisting of material with parameters depending only on the radial variable r. For this very special case, we show that the problem of determining the three functions characterizing the cloaking medium, namely, the radial mass density, the tangential mass density, and the compressibility, reduces to solving a well defined inverse problem for the Schrödinger equation. In particular, a concrete procedure is introduced for determining two of the above three functions in terms of the radial mass density via the solution of a Riemann–Hilbert problem.
