Abstract :
We demonstrate THz pulse propagation on a 25-cm-long semi-cylindrical aluminum plate with low loss and negligible dispersion via whispering-gallery modes. This represents the first demonstration of these modes on a curved metallic surface in the THz regime, and is important for implementing curved waveguides based on parallel metal plates.
