Abstract
The insertion of a metamaterial (MTM) lens based on Closed Loop Resonator (CLR) into a needle microwave applicator is investigated for a more efficient hyperthermia cancer therapy. Several geometries are designed and optimized, Closed Circular-Ring Resonator (CCRR) with circular loops and Closed Square-Ring Resonator (CSRR) with square loops, with one or more concentric loops. The MTM lens is bended around to the radiating section of the antenna to form a cylindrical 3D structure. Preliminary investigations have been focused to increase the device feasibility and patient wellness. The applicator is a slot coaxial antenna inserted into a surgical needle of 16 G and operating around at the center of Industrial, Scientific, and Medical (ISM) frequency band. The experimental results pertaining to a preliminary fabricated prototype of needle applicator are encouraging, and the simulation results suggest that they could be improved by using the investigated MTM lens.
研究了一种基于闭环谐振器(CLR)的超材料(MTM)透镜插入针微波应用器中,以提高热疗癌症的效率。设计和优化了几种几何形状,环形闭合环谐振器(CCRR)和方形闭合环谐振器(CSRR),具有一个或多个同心圆环。MTM透镜绕天线的辐射部分弯曲以形成圆柱形三维结构。初步调查的重点是提高设备的可行性和患者的健康。应用器是一根插在16g的手术针上的槽形同轴天线,在ISM (Industrial, Scientific, and Medical)频段中心工作。初步制作的针涂器样机的实验结果令人鼓舞,模拟结果表明,使用所研究的MTM透镜可以改善针涂器的性能。
