利用时域有限差分（FDTD）技术作为热疗器的设计工具，研究了具有异质组织分布的2-D电场型热疗器的基本局限性。这种设计工具使设计者能够比实验更快地研究想法。该技术进行了描述和E-场施加器的基本限制，包括一个意外的电容耦合模式中发现的一些电偶极子配置的解释。E喷头的数值研究的结果进行了总结，并证明了实用的FDTD技术作为一个喷头的设计工具。<>
The fundamental limitations of 2-D electric-field-type applicators with heterogeneous tissue distributions are studied using the finite-different time-domain (FDTD) techinque configured as a hyperthermia applicator design tool. This design tool allows the designer to investigate ideas much more rapidly than could be done experimentally. The technique is described and the fundamental limitations of E-field applicators, including an unsuspected capacitive-coupling mode found in some electric dipole configurations is explained. The results of a numerical study of E applicators are summarized, and the utility of the FDTD technique as an applicator design tool is demonstrated.<>
