Generalized retrieval method for metamaterial constitutive parameters based on a physically driven homogenization approach
Generalized retrieval method for metamaterial constitutive parameters based on a physically driven homogenization approach
Based on the recently introduced homogenization theory developed by Al\`u [Phys. Rev. B 84, 075153 (2011)], we propose a generalized retrieval method that allows extracting physically meaningful bulk effective parameters from conventional scattering measurements of periodic metamaterial samples composed of subwavelength inclusions. We show that, compared to conventional approaches, our …
