%X 我们提出了一个由三个无源谐振器组成的高阶系统的结构，近年来，相干完美吸收在各个方面受到越来越多的关注。相干完美吸收可以用于传感器的研究，我们将基于三态PT对称系统，通过分别对任何一个暗谐振器施加非本征扰动，我们可以清楚地观察到与微扰的立方根相关的频率响应。<br />
We present the structure of a higher-order system consisting of three passive resonators, which have attracted increasing attention in recent years for coherent perfect absorption. Coherent perfect absorption can be used for the study of sensors, and we go over it based on a three-state PT symmetric system. The frequency response associated with the cubic root of the perturbation is clearly observed by applying a non-eigenetic perturbation to any of the dark resonators separately.
