摘要

在本文中,我们模拟了在超材料传输线中获得的电磁感应透明(EIT)效应,在传输线的两侧放置两个交叉耦合的srr。在类eit传输带中观察到2ns和3ns之间的群延迟增加。我们演示了在15%范围内通过将垂直间隙从线移到线来调整类似eit的频率的可能性。其次是相对于基本情况在±1.2dB范围内的类似eit的幅度变化。如果将水平间隙的位置向左和向右改变,则类eit频率在13.7%的范围内发生变化,但随后透射系数和反射系数发生较大变化,因此可以通过调谐的方式来开关类eit响应。

Tuning EIT-like response in cross coupled SRRs
In this paper we present mimicking of the electromagnetically induced transparency (EIT) effect, obtained in metamaterial transmission line loaded with two cross coupled SRRs placed at the opposite sides of the line. The increased group delay between 2ns and 3ns is observed in the EIT-like transmission band. We demonstrate possibility of tuning the EIT-like frequency in the range of 15% by shifting the vertical gaps far from the line and to the line. That is followed by the change of the EIT-like magnitude in the range ±1.2dB in respect to the basic case. If changing the position of horizontal gaps to the left and to the right, the EIT-like frequency changes in the range of 13.7%, but is followed with great change of the transmission and reflection coefficients, so that way of tuning can be used to switch ON/OFF the EIT-like response.
