摘要：
Dual-band operation for terahertz (THz) wireless systems to merge multiple systems into a single one is a challenging problem. We propose a dual-band THz polarization converter using metasurfaces in transmission modes. It is singly layered which makes it a very simple structure. Dual-band conversion from linear wave to circular wave is reported over 20% of centre frequencies (1.6-1.97 THz, 3.35-4.16 THz) which is very broadband.Idea is verified by simulation and experiment.
