| 摘 要： | We report a theoretical demonstration for the creation of space–time holes based on birefringence of reflection,transmission, and the Goos–H?chen(GH) shifts from a chiral medium. We observed space–time holes in the reflection, transmission, and their corresponding GH-shifted beams. Two space–time holes are clearly detected in the regions of 0 < t ≤ 5τ_0 and-5 w ≤ y ≤ 5 w, as well as in the regions of-5τ_0≤ t ≤ 0 and-5 w ≤ y ≤ 5 w.These space–time holes hide objects and information contents from observers and hackers. The objects and information contents are completely undetectable, and thus events can be cloaked. The results of this paper have potential applications in the invisibility of drone technology and secure communication of information in telecom industries.
