Algoritmo para la caracterización univoca de metamateriales basados en inclusiones quirales

Abstract

Electromagnetic characterization is perfomed from the reflection and transmission coefficients by making use of retrieval algorithms. However, it is known the existence of uncertainties in the determination of these electromagnetic parameters. Here, we present a new algorithm that uses some techniques in order to avoid these uncertainities, some based on continuity conditions of physical magnitudes and some others based on causality relations, that is, exploiting Kramers-Kronig relations.
