Normal incidence narrowband transmission filtering in zero-contrast gratings
Xuan Cui, Hao Tian, Yan Du +3
We report narrowband transmission filtering based on zero-contrast grating (ZCG) reflectors at normal incidence. Computational results show that the filtering is realized through s…

Broadband high reflectivity in subwavelength-grating slab waveguides
Xuan Cui, Hao Tian, Zhongxiang Zhou
We computationally study a subwavelength dielectric grating structure, show that slab waveguide modes can be used to obtain broadband high reflectivity, and analyze how slab wavegu…

Novel lithium-nitrogen compounds at ambient and high pressures
Yanqing Shen, Artem R. Oganov, Guangri Qian +3
Using ab initio evolutionary simulations, we predict the existence of five novel stable Li-N compounds at pressures from 0 to 100 GPa (Li13N, Li5N, Li3N2, LiN2, and LiN5). Structur…
