Self-adaptive invisible antenna trough waveform-depended mantle cloak

The aim of this contribution is to describe 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 cloaking metasurface (MTS) made of a meander-like unit cell loaded with a lumped-element circuit. Due to the engineered time-domain response of the lumped circuit, the antenna is able switching its behavior when interacts with either a pulsed signal (PW) or a continuous signal (CW). The proposed configuration paves the way to a new generation of self-adaptive cloaking devices for antenna applications
