摘要

This article presents a tunable ferrite-based anisotropic reflective metasurface,which provides a method to manipulate the TE and TM polarized waves separately,and has much stronger ability to control electromagnetic waves andprovides different phase difference between two reflected polarized waves. Thiseventually leads to various polarized reflected waves starting from linear polarizationto RHCP and LHCP. Ferrite slab is used for realizing anisotropicbehavior. A novel method for tunability of single polarization response isobserved. A wired dipole antenna operating at 3.5 GHz is designed abovemetasurface at height d. 95 k A/m of DC biasing is applied in both X and Ydirections in ferrite-based metasurface to obtain RHCP and LHCP reflectedwaves from linearly polarized incident waves from metasurface. Moreover,polarization switchable dipole antenna is realized by changing the biasingdirection. Furthermore by varying biasing, tunability of AR is realized from 3.3to 4 GHz. The metasurface is simulated and designed on HFSS v.16.
