Abstract: (2284 Views)
We have designed an ultrathin metamaterial absorber which is capable of total absorption of the incident electromagnetic waves in the terahertz regime. Results demonstrate that the absorber is sensitive to the polarization and can operate at a wide range of incident angles under both transverse electric (TE) and transverse magnetic (TM) polarizations. The absorbance for s-polarized (TE) and p-polarized (TM) waves are 99.14% at 8.14 THz and 96.45% at 5.95 THz, respectively. The absorption frequency can be dynamically tuned by the geometries of the absorber. This terahertz metamaterial structure can be used in novel THz applications such as polarization detectors, polarization imaging, THz sensing, and polarization multiplexing.
