Abstract :
In this presentation, we experimentally demonstrate a broadband absorber in the terahertz (THz) spectral band. A thin silicon dioxide (SiO2) film is used as dielectric spacer. The combination of different sizes of Al squares gives rise to an absorption bandwidth over 200GHz with absorption magnitude of 90%.
