Advancements in high refractive index media: from quantum coherence in atomic system to deep sub-wavelength coupling in metamaterials

Autor: Singh, Leena, Zhang, Weili

Publikováno v: CHINESE OPTICS LETTERS, June 2020

Refractive index enhancement is crucial in the field of lithography, imaging, optical communications, solar devices and many more. We present a review of advancements in the process of designing high refractive index metamaterials, starting from quan

Tailoring Terahertz Propagation by Phase and Amplitude Control in Metasurfaces

Autor: Zheng, Jingjing, Zhang, Xueqian, Liu, Lixiang, Li, Quan, Singh, Leena, Han, Jiaguang, Yan, Fengping, Zhang, Weili

Publikováno v: J Infrared Milli Terahz Waves (2017)

Using metasurfaces to control the wave propagation at will has been very successful over the broad electromagnetic spectrum in recent years. By encoding specially designed abrupt changes of electromagnetic parameters into metasurfaces, such as phase

Terahertz sensing of highly absorptive water-methanol mixtures with multiple resonances in metamaterials

Autor: Chen, Min, Singh, Leena, Xu, Ningning, Singh, Ranjan, Zhang, Weili, Xie, Lijuan

Publikováno v: Optics Express, June 2017

Ultrasensitive terahertz sensing of highly absorptive aqueous solutions remains challenging due to strong absorption of water in the terahertz regime. Here, we experimentally demonstrate a cost-effective metamaterial-based sensor integrated with tera

Ultra-high terahertz index in deep subwavelength coupled bi-layer free-standing flexible metamaterials

Autor: Singh, Leena, Singh, Ranjan, Zhang, Weili

Publikováno v: JOURNAL OF APPLIED PHYSICS 121, 233103 (2017)

We report extensive enhancement in the refractive index of artificially designed metamaterials by exploiting the deep subwavelength coupling in a free-standing, thin-film metal-dielectric-metal checkboard structure. A record high refractive index of
