在之前，已對廣角入射X光波導管之垂直波導效應做過研究，如今希望能更進一步的研究此X光波導管分光之可行性，並且分析不同設計之分叉波導管的理論結果。波導管是以四吋矽晶片蝕刻，外表再於上下兩面鍍金，X光以廣角入射波導管，產生繞射光沿著表面行進。主要應用了波導原理及掠角入射波導管之駐波現象，當作分叉波導管之理論基礎。分叉波導管會由於不同夾角、不同寬度、不同設計而產生不一樣的結果，再分別比較其差異。

The mechanism of beam compression in wide-angle incident x-ray waveguides has almost been understood, and now we turn our attention to the feasibility of beam splitting in wide-angle incident x-ray waveguides, and analysis of the theoretical grounds of splitting wave guides of different design. The waveguides were prepared from a 4-inch Si crystal wafer by using ICP process and coating with gold on both sides. An X-ray beam is coupled into the waveguides at wide-angle incidence, and the surface diffraction wave then propagates through the waveguides. The theoretical considerations on waveguiding and propagation of x rays in a planar waveguide are the main theme of this study. Results on waveguiding, beam splitting, and interference for waveguides of different width and angle of incidence will be reported and discussed.
