摘要：

We propose a feasible way of guiding terahertz waves along V grooves whose lateral dimensions are subwavelength. A plasmonic metamaterial is built by periodically corrugating these channels in such a way that the system supports the propagation of electromagnetic modes with characteristics mimicking those of channel plasmon polaritons in the optical regime. These geometrically induced guided modes present long propagation lengths and low bending losses, making them excellent candidates for routing terahertz waves at planar surfaces.
