根絕緣偶極天線 (IDA) 的近場區內單位質量能量吸收率分析

Abstract

在醫學治療方面的應用愈受重視，它可以應用在癌症、攝 D等其它症狀的 治療。微波熱療法的優點在於加熱器所造成的加 耤C當我們使用間隙式微 波熱療法於惡性腫瘤的治療時，絕緣偶 @為局部加熱的加熱器。關於單根 絕緣偶極天線的臨近區域的單位質量能量吸收率 (SAR)陶\多種數值方法 提出。在本篇論文，我們採用了 Iskander-Tumehg積分較為簡便，而且我 們也採用對稱平移的方法以降低計算時的負荷。經由 S11y分佈與單位質 量能量吸收率 (SAR) 分佈的計算我們以此分析各種不同型式的天線。 In recent years, the application of microwavemedical treatment is being emphasized. Microwave hyperthermia can be used to treatprostatic hyperplasia, and so on. The advantage of microwave hyperthermiated volume coupled with the applicator is well defined. Insulated(IDAs) are often used as applicators to produce localized heating forcrowave hyperthermia treatment of cancerous tumors. Various kinds ofds were proposed to calculate the SAR distribution in the near field of athis thesis, Iskander-Tumeh approach is adopted and modified to take intonslational symmetry to improve the computation efficiency. Various types ofed through their S11 (reflection coefficient), current distributionSAR distribution.
