本文研究了基于微带加载变容二极管的非线性单负超材料。研究发现，通过在微带线上加载变容二极管和片式电感，可以实现非线性负介质，包括非线性负ε介质（NLENM）和非线性负μ介质（NLMNM），并且它们的传输间隙可以方便地由信号功率来控制。此外，还研究了NLMNM与ε-负超材料（ENM）构成的异质结构的非线性特性，结果表明NLMNM-ENM异质结构的透射特性，特别是隧道峰的透射率也可以通过信号功率进行调节。该方法在信号功率控制的微波开关中具有重要的应用前景。
In this paper, the nonlinear single negative metamaterials (NLSNM) based on the microstrip loaded with varactor diodes are investigated. It is found that the NLSNM, including nonlinear epsilonnegative metamaterial (NLENM) and nonlinear mu-negative metamaterial (NLMNM) can be realized by loading varactor diodes and chip inductors onto the microstrip, and their transmission gaps can be controlled conveniently by the signal power. In addition, the nonlinear property of the heterostructure constructed of NLMNM and epsilon-negative metamaterial (ENM) is also studied, and the results show that the transmission property, especially the transmittance of the tunneling peak of the NLMNM-ENM heterostructure can also be regulated by the signal power. The NLSNM may have important potential applications in the microwave switch controlled by the signal power.
