Abstract
Manipulation of electromagnetic (EM) waves using metasurface is enthusiastically in research nowadays. For the last decades, beam tilting, polarization control, and various mechanisms of EM waves manipulation utilizing metasurface have been reported. However, with the fixed geometry, static metasurface can be utilized only for a certain environment. To overcome the limitation of the static metasurface, recent research on dynamic metasurface has demonstrated a new horizon. This paper presents a reconfigurable metasurface utilizing a liquid crystal substrate designed based on Huygens’ principle for EM wave reflection in X-band. With a normal incident wave, different reflection angles along with high efficiency are observed. The results agree well with the numerical calculation. This paper demonstrates the rigorous design methodology of the reconfigurable metasurface reflector in detail which can be applied to radar systems and beam-forming applications.
