Metamaterial-inspired bandpass filter for the terahertz Goubau line
Résumé
Recently, it has been shown that a single wire Goubau line that supports surface wave propagation can be used as an effective terahertz waveguide with low attenuation and low dispersion. In order to fully exploit Goubau lines in terahertz systems, for example for communication applications, structures such as different types of passive filters are required. This paper demonstrates that metamaterial elements can be used as building blocks for realization of compact bandpass Goubau line filters
