Stacked rings for terahertz wave-guiding

Stefano Alberti, Jean-Philippe Ansermet, Jean-Philippe Hogge, Emile Jacques de Rijk, Alessandro Macor

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the H E11 mode. This simple concept opens the way fo ...
