论文摘要
这项研究将注意力集中在间质微波高温上，这是治疗含有肿瘤病理人体组织的流行医学程序。在论文中，使用2D有限元分析将同轴天线的模型与一个，两个和三个空气插槽进行比较。实现的模型基于在TM模式下与PENNES方程在瞬态状态条件下的波动方程。此外，该模型考虑了天线工作频率为2.45 GHz的人体组织的热电特性。已经提出了不同组织和各种多槽天线构型的仿真结果。本文中显示的单，双槽和三槽同轴天线的比较分析在高温领域的当前文献中没有等效。
This study focuses attention on interstitial microwave hyperthermia, which is a popular medical procedure for treatment of pathological human tissues containing tumors. In the paper, the 2D finite element analysis is used to compare the models of the coaxial antenna with one, two and three air slots. The implemented models are based on the wave equation in the TM mode coupled with the Pennes equation under a transient state condition. Moreover, the model takes into account the thermo-electrical properties of human tissue for the antenna operating frequency of 2.45 GHz. Simulation results for different tissues and various multi-slot antenna configurations have been presented. The comparative analysis for single-, double-and triple-slot coaxial antennas shown in this article does not have equivalents in the current literature in the field of hyperthermia.
