Description
Here a simple and reproducible method for obtaining terahertz
metasurfaces formed from multiwall carbon nanotubes (MWCNTs) is presented.
The metasurfaces were obtained from a vertically aligned array of MWCNTs using
a laser engraving technique followed by polymer covering. The structures under
study demonstrate frequency-selective re ection in terahertz range following the
Huygens{Fresnel formalism. For a normal incidence of the electromagnetic wave,
the model for numerical calculation of backscattering from the metasurfaces was
proposed. Lightweight and compact MWCNT-based metasurfaces are capable
to replace conventional pyramidal absorbers and proved to serve as a versatile
platform for scalable cost-ecient production of ultra-light electromagnetic
components for THz applications.
