Abstract. Limits for propagation of the azimuthally symmetric electromagnetic E₀  modes  along the dissipative both conductive and dielectric (water) rods were experimentally determined. It was shown that propagation of the Sommerfeld surface wave in a conductive rod is limited by the condition of equality skin-depth and the rod radius. As for the propagation in microwave range E₀ wave inside the water-rod analogously with “opto-fiber”, it is limited by the cutoff frequency of dielectric waveguide, without any dependence on salt concentration in water.
