In this paper, we propose a symmetric dual metasurface-based waveguide. The metasurfaces provide a duality impedance, which can support a linear edge mode at the interface of the metasurfaces. The mode is a very confined TEM mode and is protected against backscattering. The metasurfaces are implemented by a couple of complementary structures. One is a bed of nails and the other is a holey structure.
