Ultra-broadband terahertz absorption by exciting the orthogonal diffraction in dumbbell-shaped gratings
Metamaterials, artificial electromagnetic media consisting of periodical subwavelength metal-based micro-structures, were widely suggested for the absorption of terahertz (THz) waves. However, they have been suffered from the absorption of THz waves just in the single-frequency owing to its resonanc...
