  2. Finally in chapter 6, the problems of boundary conditions and incident wave, as the most valuable problem of mrtd as a time - domain method, are studied. this chapter presents the simulation results of the electromagnetic propagation and its interactions with the dielectric slab and analyse of the graph of the reflection coefficient in frequency. compared with fdtd results, the numerical results, obtained using the mrtd method, show the directness and conciseness of mrtd as a time - domain method and the advantages in grid enlargement and saving computer resource etc.

    最後,第六章討論了mrtd作為時數值技術最具實際應用價值的邊界條件設置和入波加入等問題,並給出模擬電磁波傳播過程和介質板系數譜分析,其數值結果表明了mrtd作為時方法的直觀簡練,與fdtd方法的結果比較,顯示了其在擴大網格、節省算資源等方面的優勢。
