摘要
用一段刚性同轴线制作的微细单极天线在医疗上已得到广泛应用。本文给出了单极天线在有耗介质中的近场分布的数值解，进而在有耗介质中测定了温度分布和ＳＡＲ图，利用近场分布计算的ＳＡＲ图和测定的ＳＡＲ图基本相符。
The monopble applicator made of rigid coaxial cable has been applied extensively in medical treatment. In this paper an expression for the electric field near the monopole applicator in derived and calculated by direct numerical evaluation of a surface integral over the insulation. The SAR patterns obtained from the calculated electric field intensity agree approximately with the measured SAR distribution in muscle-equivalent phantoms.
