Wideband terahertz absorber based on Mie resonance metasurface
Source abstract
Abstract
Terahertz absorber has attracted much attention. However, most of them have complex structures and narrow bandwidth. Here, a wideband terahertz metasurface absorber based on Mie resonance is demonstrated. The metasurface absorber is prepared by combining four dielectric resonators with different permittivity values into a single unit cell. The absorption of the wideband metasurface absorber goes beyond 80% from 8.37 to 8.60 THz, showing wideband absorption performance. In addition, the center frequency of the wideband metasurface absorber can be tuned by the size and permittivity of the dielectric resonators, which makes the proposed absorber suitable for applications in wideband terahertz devices.
