Thz coupler
WebbTHz radiation is a part of an electromagnetic spectrum lying between microwaves and the far-infrared radiation (FIR). This region has frequencies ranging from 0.1 to 10 THz and wavelengths from 3 mm to 0.03 mm. THz radiation possesses properties inherited from both microwaves and IR. Webbmagnetic coupling at THz frequencies, showing simulated Q of 65 and experimental Q of about 10.27 Zhang et al. proposed the coupling of two magnetic modes in THz metasurface, and experimentally achieved a Q-factor of 15 at 0.75 THz.28 Note that recently, localized magnetic plasmon skyrmions exhibit high-Q performance and strong
