摘要：

In order to investigate the transmission performance of a uniaxially anisotropic left-handed material waveguide, the characteristics of the guided modes of a uniaxially anisotropic left-handed material slab waveguide were studied. The characteristic equations of the guided modes in this waveguide were derived. The fast and slow wave characteristics of the guided modes were investigated. It was found that the non-surface wave modes of the uniaxially anisotropic left-handed material slab waveguide are different from that of the right- or left-handed waveguide. These modes can be either fast wave mode or slow wave mode; there is a cut-off frequency for the non-surface wave even modes; and the surface wave modes are all slow wave modes. The conditions that the characteristic equation of the surface wave has a solution was also explored. The relationship between the electromagnetic parameters of the waveguide and the solution of the characteristic equation of the surface wave modes was discussed. It was found that the surface waves with the same frequency sometimes can have two modes. The orthogonality of guided modes was proven.
