A pulse hard source has been adjusted to allow the reflection wave pass by the source without retroreflection . and the calculation area is changeable at the different time step , so only those area with wave propagation have been calculated . as the results , the total calculation time can be reduced 還有計算區(qū)域隨時間改變的方法,利用fdtd計算空間點的鄰近性,在不同的時間步上計算不同大小的區(qū)域,使得只有波傳播到的區(qū)域被計算,這樣可以縮短計算時間。
