Capacitively-Coupled Resonators for Terahertz Planar-Goubau-Line Filters

Juan Cabello-Sanchez et al.

Summary: Planar Goubau lines show promise for terahertz (THz) applications, but existing filters lack clear design procedures. In this study, we propose a design for a bandpass/bandstop filter by periodically loading the line with capacitively-coupled lambda/2 resonators. The filter's working principle is explained using a transmission-line model. We fabricated and tested a passband filter centered at 0.9 THz on a 10-µm silicon-membrane substrate, demonstrating good agreement between measurements and simulations.

Miniaturized Spoof Surface Plasmon Polaritons Load for Planar Terahertz Circuit Application on Thick Substrate

Qing Le Zhang et al.

Summary: This brief introduces a miniaturized spoof surface plasmon polaritons (SPPs) load for planar terahertz (THz) circuit applications on thick substrate. The proposed SPP cell consists of a groove-shaped structure integrated with a folded stub, which enables large capacitance, reduced cutoff frequency, and miniaturization of the SPP size. The SPP load made of nickel (Ni) metal has high conductivity and high permeability, effectively absorbing the propagating electromagnetic wave.
