非线性电超材料

Nonlinear Electric Metamaterials

David A. Powell, Ilya V. Shadrivov, Yuri S. Kivshar

摘要:

我们提出并设计了一种新型的非线性超材料,在微波频率下表现出谐振电响应。通过在每个谐振器中引入变容二极管作为非线性元件,我们能够通过改变入射功率来移动电模式阻带的频率,而不影响磁响应。这些元件可以与先前开发的非线性磁性超材料相结合,以创建控制电和磁非线性的负折射率介质。

英文摘要:

We propose and design a new type of nonlinear metamaterials exhibiting a resonant electric response at microwave frequencies. By introducing a varactor diode as a nonlinear element within each resonator, we are able to shift the frequency of the electric mode stop-band by changing the incident power, without affecting the magnetic response. These elements could be combined with the previously developed nonlinear magnetic metamaterials in order to create negative index media with control over both electric and magnetic nonlinearities.
