Some novel methods are studied in this paper. Firstly, the author studies DGFs in chiral medium avoid us ingwave field decomposition and eigenfunction expansion methods.

一些文献探讨了旋波媒质中电磁场矢量及其DGF的形式,这些文献从各自角度探讨了旋波媒质中依赖于电磁波场本征问题的DGF形式,但都存在局限性。

Using finite difference time domain method, the electromagnetic field distribution of THz wave is simulated in a THz 2D PC splitter and by plane wave expansion method the dispersion relation and defect modes are achieved in a THz rotated PC waveguide.5. A woodpile three-dimensional (3D) PC with face-centered-tetragonal symmetry is one of the most popular 3D PCs because of its favorable band gap characteristics. Based on the woodpile fct lattice structure, we propose a novel woodpile THz lattice structure with comparatively decreased symmetry, better band gap properties and easy fabrication by varying some structure parameters.
