Firstly, as a forward problem is solved for each iteration of ga reconstruction, calculating the electric field for a given distribution permitivity and driving source - this aspect will be treated with more detail. the thesis uses finite element method ( fem ) to solve it, because fem can conveniently handle inhomogeneous dielectric, converge well, and spare computing time by compacting the matrix
本文首先建立了介電成像的數學模型，採用有限元方法求解正問題，有限元方法的優點在於能方便地處理非均勻介質、具有良好的收斂性、可以壓縮系數矩陣而節省計算時間，這有利於應用遺傳演算法進行優化。
