Web3 de jul. de 2012 · 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).
Hiding Under the Carpet: a New Strategy for Cloaking
Web18 de set. de 2015 · The skin cloak comprises a metasurface with distributed phase shifts rerouting light and rendering the object invisible. In contrast to bulky cloaks with volumetric index variation, our device is only 80 nanometer (about one-ninth of the wavelength) thick and potentially scalable for hiding macroscopic objects. Web(b) E-field pattern showing the reflected packet from the cloak at time t = 37fs. (c) E-field pattern at time t = 37fs when the cloak is absent. All length scales are in µm. The … csaw feedback
Hiding under the Carpet: A New Strategy for Cloaking
WebThis unique design allows watching outside by hiding a sensor under the carpet cloaking without being detected from the outside. To verify this unique idea, we carry out full-wave simulation with commercial software (COMSOL Multiphysics 3.5 solver). Webwaves [11,16]. Now the concepts of cloaked sensing and cloak detection are being extensively studied [17–19]. In this work we propose a scheme for watching the outside while hiding under a carpet cloak based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak Web29 de jan. de 2016 · We propose a single low-profile skin metasurface carpet cloak to hide objects with arbitrary shape and size under three different waves, i.e., electromagnetic … dynaxicurity
