障碍物散射中的虚拟整形和不可见性
Virtual reshaping and invisibility in obstacle scattering
摘要：
我们考虑通过在声散射和电磁散射中使用变换光学来重塑散射障碍物。在一般的虚拟整形结果中，重点研究了虚拟缩小和虚拟放大。稳定性估计推导出散射振幅在一个小障碍物的直径，这意味着缩小的极限情况下对应于一个完美的隐身，即，这个障碍物是看不见的。
英文摘要：
We consider reshaping a scattering obstacle virtually by using transformation optics in acoustic and electromagnetic scattering. Among the general virtual reshaping results, the virtual minification and virtual magnification are particularly studied. Stability estimates are derived for scattering amplitude in terms of the diameter of a small obstacle, which implies that the limiting case for minification corresponds to a perfect cloaking, i.e., the obstacle is invisible to detection.
