动态变形镜的运动感应辐射
Motion-Induced Radiation from a Dynamically Deforming Mirror
摘要：
本文提出了一种路径积分公式来研究理想反射（导电）表面的辐射光谱。它使我们能够研究空间和时间的任意变形。光谱在高度函数中计算到二阶。对于表面上的谐波行波，我们发现辐射被限制在某些方向上的许多不同的区域。结果表明，高频光子发射的光束具有相对较低的角色散，其方向可以控制的机械变形的板。
英文摘要：
A path integral formulation is developed to study the spectrum of radiation from a perfectly reflecting (conducting) surface. It allows us to study arbitrary deformations in space and time. The spectrum is calculated to second order in the height function. For a harmonic traveling wave on the surface, we find many different regimes in which the radiation is restricted to certain directions. It is shown that high frequency photons are emitted in a beam with relatively low angular dispersion whose direction can be controlled by the mechanical deformations of the plate.
