Conductivity reconstruction, one kind of electromagnetic measurement, reconstructs conductive property distribution of the biological tissue exposed to electromagnetic fields by measuring the fields around it. this thesis presents the application of improved genetic algorithm to reconstruct the conductivity distribution of stratified biological tissue by measuring the change of impedance in the coil
本文主要研究在載流線圈作用下，通過測量生物組織產生的二次場對線圈阻抗的改變，應用改進的遺傳演算法重構分層生物組織各層電導率和厚度的方法。 -
The results showed that yielding the strength increase with the strain rate, the energy absorption increase with increasing strain rate and was related to the density. strain has slightly effect on the strain rate sensitivity of the solid material, but the strain rate sensitivity of fs increase with increasing true strain and also increase with incremental change in strain rate at the same true strain. the properties of thermal conductivity, electrical conductivity and electromagnetic shielding were studied
實驗結果表明，泡沫鋁的屈服強度隨著應變率的增加而增加；應變對固體材料的應變率敏感度影響很小，但是泡沫鋁的應變率敏感度不是常數，而是隨著真應變的增加而增大，在同樣的應變下，隨著應變率變化幅度的增大而增大；泡沫鋁的能量吸收隨著應變率的增加而增加並且和泡沫鋁的密度有關；泡沫鋁的吸能效率隨著應變率的增加略有下降。 -
Secondly, the human body is simulated by a model with inhomogeneous dielectric constant and conductivity hi the fdtd program to calculate the effect of stable plane wave to the human body, hi the same time the mode can be used hi ( fd ) 2td programmed to calculate the effect of electromagnetic pulse to the human body by using debye parameter
主要包括以下幾部分內容：首先，編制fdtd （時域有限差分法）和（ fd ） ~ 2td （色散時域有限差分法）程序，並驗證了這兩個軟體的有效性。其次，建立了解析度分別為4 . 25mm和1 . 31cm的實際人體電磁參數模型和色散電磁模型，建模過程中採用了圖象處理技術。
