Hybrid Fishnet Metamaterial Based on Liquid Crystal and P-I-N Diodes for Reconfigurable Transmitarrays at <inline-formula><tex-math notation="LaTeX">$10 \,\mathrm{GHz}$</tex-math><...
Published 2025-01-01“…The proposed design achieves a phase shift of up to <inline-formula><tex-math notation="LaTeX">$180 \mathrm{^{\circ }}$</tex-math></inline-formula> between different states and additional tunability in each phase state by switching the electric response using p-i-n diodes and simultaneously tuning the magnetic response by employing liquid crystal. Thus, it offers the potential to overcome the limitations of switchable unit cells with few discrete phase states in terms of achievable antenna gain and side lobe level. …”
