Chapter 5: Theoretical investigation indicates that the anomalous positive refraction can be observed at a planar interface between an isotropic positive index material and an anisotropic negative index material. When the the optical axis of uniaxial left-handed material is not normal or parallel to the interface, the refraction of Poynting power for the extraordinary waves can be either positive or negative depending on the incident angles, while the refraction of the wave vector is always negative.
第五章：从理论上分析了在各向同性的正折射率介质和各向异性的负折射率介质界面会出现反常正折射当各向异性的负折射率介质光轴角既不平行也不垂直界面时，能流会发生反常正折射，而波矢始终发生负折射。
Firstly, theinteraction between Gaussian beam and isotropic metamaterials slab is simulated, suchas negative index, phase compensation, piano-concave lens imaging. Then thenumerical results of ADE-FDTD method show that the sign ofx component of relativepermeability tensor of anisotropic metamaterials determines the refraction isregular or anomalous, whereas the sign of z component of relative permeability tensorof AMM determines the energy flow is positively refracted or negatively refracted. Thewave vector and energy flow density in AMM are not always parallel or antiparallel. Finally, the directions of the forward and backward surface and guided wave excitedinfluenced by the material parameters of AMM in multi-layered structures are analyzedwith SO-FDTD method.
