Abstract
- The “invisible carpet cloak” has recently been created and demonstrated as a novel device that serves to conceal conducting objects from external detections (J. Li and J. B. Pendry, “Hiding under the carpet: A new strategy for cloaking,” Phys. Rev. Lett., vol. 101, no. 20, p. 203901, 2008). In this work, we have explored its new function as a new type of stealth radome to protect antennas. A technique called “virtual boundary” is implemented to the carpet cloak to ensure that a conducting antenna element located beneath the carpet can transmit and receive signals, while being undetectable to the external incidences. Meanwhile, the carpet cloak functions as a novel lens to create highly directive beams. Numerical simulations based on finite-difference time-domain (FDTD) method have demonstrated the expected performances over the frequency range from 8 GHz to 12 GHz (the X-band).
