Abstract
We introduce a reconfigurable metasurface that can dynamically alter the phase distribution on its surface by controlling the external bias voltage. This metasurface not only mimics the electromagnetic shape of other objects at 6 GHz but also hides arbitrary objects within the frequency range of 4–7 GHz. The metasurface consists of 6 × 6 supercells, with each supercell including 4 × 4 identical capacitive sub-cells. We choose a trapezoid as a test object to demonstrate the illusion capabilities of the reconfigurable metasurface. To verify its stealth functionality, we adopt two methods: placing the object to be concealed either below or above the metasurface. Our designed reconfigurable metasurface possesses both illusion and stealth capabilities.
