Quite recently, it was found that metal wires can effectively guide terahertz radiation. Based
on the fact that the absolute values of the relative permittivities of metals in the spectral …

We describe the experimental realization of planar plasmonic THz guided-wave devices

Terahertz transmission filters have been manufactured by perforating metal films with
various geometric shapes using femtosecond laser machining. Two dimensional arrays of …
