论文摘要
我们介绍了能够根据接收/发射信号的波形自动隐藏或揭示其存在的创新线天线的设计。这种非常规的行为是通过使用新型波形选择性的覆盖式跨表面实现的，该覆盖层剥削了一个蜿蜒的类似单元电池，该单元带有大量元素电路，能够根据撞击信号的波形来设计天线的散射。由于总元素电路的时域响应，当与脉冲波（PW）或连续波（CW）信号相互作用时，天线能够切换其散射行为。提出的配置为智能天线系统的新一代掩盖设备铺平了道路，扩展了天线作为能够感知外部环境并相应地改变其电磁行为的设备的概念。
We present the design of an innovative wire antenna able to automatically hide or reveal its presence depending on the waveform of the received/transmitted signal. This unconventional behavior is achieved through the use of a novel waveform-selective cloaking metasurface exploiting a meander-like unit cell loaded with a lumped-element circuit capable to engineer the scattering of the antenna depending on the waveform of the impinging signal. Due to the time-domain response of the lumped-element circuit, the antenna is able switching its scattering behavior when interacts with either a pulsed wave (PW) or a continuous wave (CW) signal. The proposed configuration paves the way to a new generation of cloaking devices for intelligent antenna systems, extending the concept of antenna as a device capable to sense the external environment and change its electromagnetic behavior accordingly.
