Dual Polarization (TE and TM) Terahertz Spoof Surface Plasmon Polaritons Enabled by Metasurface

Surface plasmon polaritons (SPPs) have important applications in many aspects. In this paper, we study a three-layer structure that can support surface plasmon polaritons in the terahertz regime. And this structure supports both TE and TM polarized SPPs. We also use the electromagnentic field simulation software to calculate the dispersion.
