摘要

本文描述了在平衡频率处指数为零的可重构平衡传输线内部的异常多普勒效应。通过应用数字信号控制器，在该传输线内建立了移动反射接口。在不同的频率下观察到正多普勒效应、逆多普勒效应和零多普勒效应，从而完整地描述了超材料中的多普勒效应。

Doppler effect in zero-index metamaterials

This paper presents our observation of the abnormal Doppler effect inside a reconfigurable balanced transmission line, which has zero index at the balanced frequency. By applying a digital signal controller, a moving reflective interface is built inside this transmission line. The normal, inverse and zero Doppler effects are observed at different frequencies, which gives a completed picture of Doppler effect in metamaterials.
