Position effect of split ring resonators along terahertz planar Goubau line

In this communication, we study the effect of the position of SRR on the resonance frequency of the planar circuit. The idea is to better control the position of SRR along the Planar Goubau Line (PGL) in order to attain maximum rejection. This result is important for the design of terahertz circuits. As a demonstration of the flexibility and scalability of the designs, we show experimental results, which are in good agreement with simulations, from 140 to 200 GHz. This principle can be easily scaled at higher terahertz frequencies.
