论文摘要
明智的增益和损失设计导致保守系统无法访问的违反直觉波浪现象。值得注意的是，此类设计可以引起激光吸附模式和各向异性传输共振。在这里，我们分析了这些现象在光散射器中的出现，并具有正弦增益减损的调制，该调制受到单色倾斜波。我们为问题提供了一个分析解决方案，我们通过该解决方案显示了散点器参数，特别是调制阶段和入射角如何构成访问这些现象的真实设计空间。
A judicious design of gain and loss leads to counterintuitive wave phenomena that are inaccessible by conservative systems. Notably, such designs can give rise to laser-absorber modes and anisotropic transmission resonances. Here, we analyze the emergence of these phenomena in an optical scatterer with sinusoid gain-loss modulation that is subjected to monochromatic oblique waves. We derive an analytical solution to the problem, with which we show how the scatterer parameters, and specifically the modulation phase and incident angle, constitute a real design space to access these phenomena.
