COMPUTER AIDED MEASUREMENT OF THE ELECTRO- MAGNETIC PARAMETERS FOR THE MICROWACE ABSORBING MATERIALS

摘要: 微波吸收材料的电磁参数在评价吸收剂性能时是一个重要指标。参数重建属于电磁逆散射问题,而传统的阻抗方法仅利用正好足够的测试数据来获取电磁参数,未能利用冗余数据对材料的电磁性能作综合评定。本文介绍结合网络参数的多点测量阻抗的优化方法,在测量线上实现了电磁参数的自动测量。文中给出了标准样品和吸收材料的实测结果。Abstract: A novel method involving multiple impedance measurements and optimization algorithm for the reconstruction of electromagnetic parameters is presented. Computer-aided analysis is used in all processes. Experimental results including teflon and some kinds of microwave absorbing materials are given.
