我们提出了一般的概念，掩盖传感器，而不影响其能力，接收，测量和观察传入信号。这可以通过使用等离子体传感器来获得，该等离子体传感器基于隐身，由在红外和光学频率下自然可用的材料制成，或者可实现为在较低频率下的超材料。结果是可以接收和发送信息的感测系统，而其存在不会被周围环境感知，这在广泛的生物学、光学、物理学和工程应用中可能具有根本的重要性。
We propose the general concept of cloaking a sensor without affecting its capability to receive, measure, and observe an incoming signal. This may be obtained by using a plasmonic sensor, based on cloaking, made of materials available in nature at infrared and optical frequencies, or realizable as a metamaterial at lower frequencies. The result is a sensing system that may receive and transmit information, while its presence is not perceived by the surrounding, which may be of fundamental importance in a wide range of biological, optics, physics, and engineering applications.
