“…In our former work, we firstly deduced the quantum features of NRI of the lossless mesoscopic left-handed transmission line (LH-TL) [28]. Then we quantized the lossy LH-TL [29] and we discussed the quantum influence of dissipation on the NRI [29] in a displaced squeezed Fock state. And some novel quantum effects were revealed and were reputed significance for the miniaturization application of LH-TL.…”

The refraction index of the quantized lossy composite right-Left handed transmission line (CRLH-TL) was deduced in the thermal coherence state. The results show negative refraction index (herein the left-handedness) can be implemented by the electric circuit dissipative factors(i.e., the resistances R and conductances G) in the higher frequency bands (1.446GHz≤ ω ≤ 15GHz), and flexibly adjusted by the left-handed circuit components (C l , L l ) and the right-handed circuit components (Cr, Lr) at a lower frequency (ω=0.995GHz) . The flexible adjustment for left-handedness in a more wider bandwidth will be significant to the microscale circuit design for the CRLH-TL and may pave the theoretical preparation for its compact applications.

“…In this context, a natural question is * Corresponding author: zhaosc@kmust.edu.cn what's the role of quantum mechanical properties in the mesoscopic CRLH-TL when its compact size approaches the Fermi wavelength [25,26]. Thus, the understanding of how the quantum mechanical behaviors alter the positive/negative refraction index [27,28] in the quantized CRLH-TL [29,30] is of crucial importance. Addressing these clearly requires a quantum description of the CRLH-TL, as is the main motivation of the present work.…”

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.

Design of an optically-transparent ultra-broadband microwave absorber

et al. 2023

The optical window of the low-observable platform needs to be compatible with ultra-broadband absorption, hence an optically-transparent absorber with ultra-broadband absorption is designed and analyzed in this paper. The transparent materials indium-tin-oxide (ITO) film and polymethylmethacrylate (PMMA) are selected as the lossy layer and the supporting dielectric layer, respectively. The optically-transparent ultra-broadband absorber (OT-UBA) is composed of three layers of ITO square patterns, three layers of PMMA dielectric and a uniform ITO plane. The ITO square patterns can realize arbitrary equivalent series RC (resistor & capacitor) circuit, so that three layers of ITO square patterns together with the ITO plane can achieve ultra-broadband absorption based on the equivalent circuit optimization. Measured results shows that the 90%-absorption bandwidth covers 2-17 GHz while the light transmittance achieves 59.6% with the total thickness of only 12.9 mm.
