摘要: 微波吸收材料的電磁參數(shù)在評價吸收劑性能時是一個重要指標(biāo)。參數(shù)重建屬于電磁逆散射問題,而傳統(tǒng)的阻抗方法僅利用正好足夠的測試數(shù)據(jù)來獲取電磁參數(shù),未能利用冗余數(shù)據(jù)對材料的電磁性能作綜合評定。本文介紹結(jié)合網(wǎng)絡(luò)參數(shù)的多點(diǎn)測量阻抗的優(yōu)化方法,在測量線上實(shí)現(xiàn)了電磁參數(shù)的自動測量。文中給出了標(biāo)準(zhǔn)樣品和吸收材料的實(shí)測結(jié)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.
