| Popis: | A tunable flat lens is demonstrated based on reconfigurable metasurface, which is realized via changing the phase gradient of the metasurface in sub-wavelength level. The sub-wavelength metamolecules are formed by enclosing a liquid metal plug within microfluidic cavities, which can be tuned by changing the geometry of the metamolecules. The tunable flat lens is consisted of soft material with controllable functionalities. In simulation, the tuning of the focal length from 5 λ to 7 λ is demonstrated as the proof of concept. This reconfigurable metasurface can be used as a standard guideline to design different electromagnetic wave manipulation systems in realizing the dynamic control of beam steering, anti-reflection and focusing functionalities etc. |
