Abstract

We present design and simulation of spoof Surface Plasmon Polariton (sSPP) delay lines with same physical length to compose a 1-bit 180ᵒ phase shifter at 1 THz. The sSPP delay lines are based on single conductor waveguide, which has rectangular and identical corrugations on both sides and is attached to a dielectric. The delay lines are engineered by determining only the corrugation depths and keeping all the other parameters same as each other. The corrugation depths of the delay lines vary between 4.5 μm and 15.75 μm. The average percentage phase error, insertion and return losses of 207 μm delay lines are %2.6, -2.2 dB and -17.54 dB at 1 THz, respectively.
