标题： Friedel Oscillations in Microwave Billiards

摘要： 电子密度在杂质附近的Friedel振荡在微波弹道中有一个对应现象，我们对此进行了测量，针对的是伪可积和混合动力学几何结构。 预期并发现这些振荡与动力学无关，并由随机平面波模型预测。 为了将混合系统的混沌态与规则态区分开来，需要以多种方式将适当的相空间投影纳入建模，以便与实验结果良好一致。 显示英文摘要

摘要： Friedel oscillations of electron densities near impurities have an analog in microwave billiards, which we measure for pseudo-integrable and mixed dynamics geometries. It is expected and found that the oscillations are independent of the dynamics and predicted by a random plane wave model. Separating the chaotic from the regular states for the mixed system requires incorporating the appropriate phase space projection into the modeling in multiple ways for good agreement with experiment.
