Abstract:	近年來RF無線射頻系統已被廣泛地運用於日常生活中，包括電子錢包、倉儲管理、身分識別、行動定位等各方面。並且由於行動電話基地台等電磁波對人體所造成之影響日趨受到重視，使得各生醫研究單位積極投入探討人體與電磁波間之交互作用，以及其所造成之影響。　　再者，植入式生醫裝置可非常廣泛地被應用。將多功能生醫裝置植入人體，以傳輸各種生理檢測資訊，或對器官、組織進行刺激、控制，未來更可發展植入式藥物釋放系統，為慢性病患、罕見疾病患者、美容業者提供更方便舒適的選擇。　　結合無線射頻技術運用於植入式生醫裝置，可利用RF提供植入式裝置能量來源、並控制回饋參數，提供即時且準確之生理訊息，拓寬了無線生醫裝置應用發展範圍。　　本研究主要探討以運用時域有限差分法（FDTD）建立之人體電磁場模型，模擬人體在不同RF頻段設定下傳輸射頻能量時，體內外SAR值大小與分布，用於評估選擇植入式無線生醫裝置之植入部位，以得到最佳之接收效率。　　The radio frequency system has been broadly applied in our daily life. The applications include electronic wallet, personnel management, personal identification, and many others. As the mobile phone stations send out electromagnetic waves which may cause damages to human body, many research organizations have conducted relative researches to find out the interactive function between human body and electromagnetic waves. 　　Moreover, implantable bio-medical devices may be extensively applied. Multi- functional bio-medical devices can be planted into a human body to transfer physiological information, or to stimulate organs and tissues. The implantable bio-medical devices may be further developed as an medicine release system, which can offer better choices to chronic patients, rare disease patients, and cosmetology. 　　Radio frequency technology can be built into an implantable bio-medical device to provide the device energy, to transmit the feedback signals and parameters, and to send out the instant and accurate physiological information. This will broaden the applications of RF-built bio-medical devices. The research in this thesis is conducted through simulating the SAR distribution of a human body under various radio frequencies. The electric magnetic field model for a human body is set up and the FDTD method is applied. The results can be used to decide the most proper positions in a human body for an implantable bio-medical device to reach the best efficiency of RF receiving.
