摘要
采用二进制粒子群算法进行拓扑优化,设计并制备了一种用于对2.45GHz频点附近电磁干扰进行防护的吸波玻璃。该材料使用经优化的单层ITO膜结构作为主吸波层,硅硼玻璃基板作为介质层,实现了2.45GHz时最大吸收率为99.996%且90%吸收率频带基本覆盖2~3GHz。该材料可用于有透光要求且对电磁干扰十分敏感的室内精密电子器件的电磁干扰防护。
According to a binary particle swarm optimization algorithm,an absorbing glass for protecting electromagnetic interference near the frequency of 2.45 GHz was designed and prepared.The glass used an optimized single-layer ITO film unit as the main absorbing structure,and a borosilicate glass substrate was used as the dielectric layer.The maximum absorption rate at 2.45 GHz is 99.996%and the 90%absorption band basically coverd 2~3 GHz.The glass can be used for electromagnetic interference protection of indoor precision electronic devices that have light transmission requirements.
