论文摘要
镜头中的波效应形成了经典苛性奇异性和量子干扰的交集，形成了丰富的现象，但众所周知，很难建模。最近观察到的脉冲星和射电天文学中的快速无线电爆发以及引力波检测器的灵敏度提高表明，可能会在不久的将来观察到波浪效应。干扰条纹对无法从几何光学元件推断的物理参数敏感。特别是，对于多平面镜头，该模式取决于晶状体平面的红移。我提出了一种新方法，用于定义并有效地评估多项式时间的等离子体和重力透镜对相干电磁波的多平面镜头。这种方法将允许使用无线电和重力波源以新颖的方式探测我们的宇宙。
Wave effects in lensing form a rich phenomenon at the intersection of classical caustic singularities and quantum interference, yet are notoriously difficult to model. A large number of recently observed pulsars and fast radio bursts in radio astronomy and the prospected increase in sensitivity of gravitational wave detectors suggest that wave effects will likely be observed in the near future. The interference fringes are sensitive to physical parameters which cannot be inferred from geometric optics. In particular, for multi-plane lensing, the pattern depends on the redshifts of the lens planes. I present a new method to define and efficiently evaluate multi-plane lensing of coherent electromagnetic waves by plasmas and gravitational lenses in polynomial time. This method will allow the use of radio and gravitational wave sources to probe our universe in novel ways.
