Quasibound states in the continuum in terahertz free-standing metal complementary periodic cross-shaped resonators
Dejun Liu, Feng Wu, Lin Chen +1
We numerically and experimentally achieve quasi-bound states in the continuums (BICs) with high-Q factors in the free-standing metal complementary periodic cross-shaped resonators…

Terahertz composite plasmonic slabs based on double-layer metallic gratings
Dejun Liu, Lin Chen, Feng Liu
A composite plasmonic slab based on double-layer metallic gratings and a dielectric film is experimentally and numerically demonstrated in terahertz (THz) regions, which can suppor…

Terahertz metallic photonic crystals integrated with dielectric waveguides
Dejun Liu, Lin Chen, Feng Liu
Compact and low-loss photonic crystal waveguides are critical in integrated terahertz (THz) applications. Compared with pure metal or dielectric photonic crystal waveguides, hybrid…
