研究了由阻抗匹配的介电常数负值和磁导率负值介质组成的平板波导的导模特性。这种特殊类型的波导只支持具有偏振简并性的单模：横向电(TE)和横向磁(TM)偏振光波总是具有相同的传播波矢。然而，这些简并的TE和TM模式的总潮流方向总是相反的。
The properties of guiding modes of a slab waveguide composed of impedance-matched epsiv (permittivity) negative and mu (permeability) negative media were investigated. This special type of waveguide supports only a single mode having polarization degeneracy: transverse-electric (TE)- and transverse-magnetic (TM)-polarized light waves always have the same propagation wavevectors. However, the overall power flow directions of these degenerate TE and TM modes are always opposite to each other.
