Abstract

Left-handedness signifies negative permittivity (ε_r) and permeability (μ_r) in the same frequency band. The ε_r and μ_r are evaluated in a quantized composite right-left handed transmission line (CRLH-TL), and the frequency band for left-handedness is also valuated in the balanced resonance (L_rC_l = L_lC_r) and unbalanced resonance (L_lC_r ≠ L_rC_l) cases in the displaced squeezed Fock state. The results show that the balanced resonance plays an important role in bandwidth and achieving for left-handedness. This displays some quantum mechanical behaviors and proposes a new potential approach to wider frequency band left-handedness for the quantized CRLH-TL.
