摘要

本文介绍了利用传输型数字超表面PIN二极管进行频率调谐的方法。在这里，当S21值小于- 8db时，PIN二极管在ON和OFF状态下的单元格的S21幅值被赋予数字代码“0”，当幅值为0db时，被赋予数字代码“1”。观察到，当二极管处于ON状态时，10 × 18阵列在4 GHz处呈现OFF状态。同样，当二极管处于OFF状态时，阵列在4 GHz处显示ON性质，从而根据二极管的状态在2.54、4、6.84 GHz处显示ON或OFF状态。这增加了操作的带宽。

Simple way of Frequency Tuning using Pin Diode of Transmission type Digital Metasurface

This article shows the frequency tuning using a PIN diode of transmission type digital metasurface. Here, the S21 amplitude of the unit cell in ON and OFF condition of the PIN diode is given the digital code of “0” when the S21 value is less than - 8 dB, and “1” when the amplitude is 0 dB respectively. It is observed that when the diode is ON, the 10 x 18 array shows the nature of OFF condition at 4 GHz. Similarly, when the diode is OFF, the array shows the ON nature at 4 GHz, thus getting ON or OFF condition at 2.54, 4, 6.84 GHz depending on the condition of the diode. This increases the bandwidth of operation.
