Monochromatic Composite Right/Left Handedness in the Quantized Composite Right/Left Handed Transmission Line

Macro composite right/left handedness (CRLH) signifies positive/negative refraction index in different frequency bands in the composite right/left handed transmission line (CRLH-TL). In this paper, the refraction index of a quantized CRLH-TL in the thermal squeezed state is visited. Performing explicit calculations on the squeezed parameters and electronic components' parameters, a novel regime for implementing CRLH with a single operating frequency via the squeezed parameters and electronic components' parameters is found. The definitely different monochromatic CRLH enriches the initial definition of CRLH, and may propose a novel direction to implement CRLH in metamaterials.
