In this chapter we study the propagation of coupled surface electromagnetic waves in a circular cylindrical waveguide (Goubau line) filled with a Kerr medium. We prove the existence of a new propagation regime in which the field is a superposition of two independent waves (TE and TM) that together generate a nonlinear polarization in the coating-what we call a coupled TE–TM wave. The TE and TM constituents that form this state are referred to as pseudo–TE and pseudo–TM waves

摘要

In this chapter we study the propagation of coupled surface electromagnetic waves in a circular cylindrical waveguide (Goubau line) filled with a Kerr medium. We prove the existence of a new propagation regime in which the field is a superposition of two independent waves (TE and TM) that together generate a nonlinear polarization in the coating-what we call a coupled TE–TM wave. The TE and TM constituents that form this state are referred to as pseudo–TE and pseudo–TM waves
