    Abstract: 本文的主旨在於探討高溫微波熱療法中生物體內電能功率與電場的分析,以了解影響體內溫度分佈的各種控制因素。為了模擬實際的加熱微波系統,文中提出了一系列的理論分析,其步驟如下:首先應用Maxwell方程式推導得電磁場能分佈之統御方程式,以及電磁場在穿過不同介質後的變化情形,然後以有限元素法推導出計算各別元素電磁場大小之方程式,得到電磁場在系統內分佈的數值解,以便進行電磁場能分佈之計算最佳化工作,進而提供系統的評估及設計的參考。在利用了此種數值方法得到初步的數據之後,為了確認我們模擬的結果是否正確,我們利用了FEMLAB套裝軟體模擬了已簡化的人體組織情況下的測試案例,以得到此模擬系統之FEMLAB解,再將數值解與此FEMLAB解互相比較,結果顯示我們的數值模式具有不錯的效率且結果也相當具有可行性。 The study presents the analysis of the power of electric energy and electric field in the organism in the high-temperature microwave hyperthermia, in order to understand the factors that influence the distribution of internal temperature. For the simulation of real heating microwave system , the study presents a series of theory analysis ,and its step is as follows: first use Maxwell equation to derive the governing equation of the system and to derive the equation of EM wave moving through the boundary of different medium ; then use FEM to derive the equation of each element, and get the approximate solution to optimize the result of the system, offering the systematic assessment and reference of the design. After using this Numerical method to get the preliminary data, we utilize the test case under the simple tissue situation of software simulation of FEMLAB in order to confirm whether the result of our simulation is correct ,and get the FEMLAB solution.Finally we compare approximate solution with FEMLAB solution,and the results show that this method have good efficiency and feasibility.
