Left-handedness in the balanced/unbalanced resonance conditions of a quantized composite right-left handed transmission line

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...

Description
Summary: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 r C l = L l C r ) and unbalanced resonance ( L l C r ≠ L r C 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. Graphical abstract
