摘要

这项贡献的目的是开发高性能短天线结构，可作为骨盆热疗(HT)应用的3D相控阵的基本阵列元件。应用时域有限差分(FDTD)方法，系统地进行了三维高温照射器基本阵列单元的数值设计。对天线设计的时域有限差分法进行了一些改进。因此，对细导线和薄层的建模进行了近似，并对适合与网络分析仪测量进行比较的源环境进行了建模。应用另一种数值工具，体积面积分方程(VSIE)进行了额外的验证。

Systematic design of antennas for cylindrical 3D phased array hyperthermia applicator

The purpose of this contribution is to develop high performance short antenna structures which can be used as basic array elements of the 3D phased array for hyperthermia (HT) applications in the pelvis. The numerical design of basic array elements of the 3D HT applicator has been performed in a systematic way applying the finite-difference time-domain (FDTD) method. Some modifications of the FDTD method specific for antenna design have been implemented. Thus, approximations for modelling of thin wires and thin layers have been made as well as source environments suitable for comparisons with network analyzer measurements have been modeled. An additional verification has been performed applying another numerical tool, the volume surface integral equation (VSIE).
