以微波治疗妇科疾病为研究背景 ,建立了医用微波辐射器的场分布模型 ,分析了辐射器的近场分布特性。分析计算结果表明 ,辐射器的能量主要集中在其四周的近场 ,而辐射器顶端的场值很小 ,并且在人体组织内能量衰减很快。应用此种辐射器可以达到治疗某些妇科疾病的目的 ,不会对正常的人体组织产生影响。对所设计的辐射器 ,给出了在治疗中的某些测试结果。分析对指导辐射器的设计具有重要参考价值

Taking microwave treatment of gynecological diseases as research background, the field distribution model of medical microwave radiators was established and the near-field distribution characteristics of radiators were analyzed. The results of analysis and calculation show that the energy of the radiator is mainly concentrated in the near field around it, while the field value at the top of the radiator is very small, and the energy attenuation in human tissues is very fast. The use of such radiators can achieve the purpose of treatment of certain gynecological diseases, will not affect normal human tissues. For the design of the radiator, given in the treatment of some of the test results. Analysis of the design of the guide radiator has an important reference value
