Gangbuster frequency selective surface metamaterials in terahertz band
Abbreviated Journal Title
FABRICATION; Engineering, Electrical & Electronic
Frequency selective surfaces using Ag dipole antenna elements have been simulated, fabricated and tested to demonstrate improved narrowband transmission compared to the current state of the art in the 1 - 2 THz. Several designs are presented including variations in dipole packing density, and sensitivity to a cladding layer. The sharpest resonant response was measured to have a bandwidth of 90 GHz at a centre frequency of 1.3 THz, for a Q of 14.5, which is the highest thus far reported for a terahertz narrowband filter. In addition, the sensitivity of the resonance of the structures to material properties may be exploited as a way to measure the permittivity and loss tangent of thin films in the terahertz band.
