Abstract

Abstract

For a planar waveguide filled with periodic parallel finite-length carbon nanotube array, we got the dielectric properties of the parallel carbon nanotube array based on the equivalent medium model for parallel carbon nanotube arrays while ignoring the spatial dispersion but considering the electromagnetic wave propagation loss, respectively, and led the electromagnetic wave propagation in the waveguide into the Hamilton system with the ideal conductive boundary conditions, then we used the symplectic theory framework to solve the eigenvalue equations for the electromagnetic wave propagation and obtain the dispersion relationships. According to the analysis, it shows that the fundamental mode for the electromagnetic waveguide can't propagate within a narrow spectrum, however, the fundamental mode propagates smoothly with very low loss elsewhere, which makes the carbon nanotube array a waveguide material with better propagation characteristics in a wide spectrum than traditional materials.
