A Surface Electromagnetic Wave on a Plane Ribbon with a Highly Conducting Surface

The properties of a surface wave directed by a plane ribbon made of a nonmagnetic material with a high surface conductivity are investigated. Using the model of an equivalent ribbon with an elliptical cross section, the complex slowing (corresponding to the real part) and attenuation (corresponding to the imaginary part) ratio is approximately calculated in the case when a wave propagates along the ribbon. Approximate estimation values for the phase, group, and energy velocities of the surface wave are also obtained.
