Erratum : Electromagnetic characterization of planar and bulk metamaterials : A theoretical study

Several errors were found in our paper. In this erratum we provide the corrected expressions for surface susceptibilities and reflection and transmission coefficients. Using the corrected formulas we reproduce the main results of the work and discuss the obtained quantitative differences. In our paper we claimed that the factors 2 in front of the term χ ES were missed in formulas (9) and (10) of Ref. 1. It was a wrong statement; actually these expressions are perfectly correct. We would like to apologize for our unjust criticism of the work in Ref. 1. Also, we made two errors [in formulas (5) and (6) of our manuscript]. We are grateful to the authors of Ref. 1, who pointed out some of our errors in their private correspondence. In this erratum we present the corrected expressions for both electric and magnetic surface susceptibilities and for both reflection and transmission coefficients of the metafilm we have derived after a thorough analysis. Notice that our corrected formulas still contain slight differences from those presented in Ref. 1 (i.e., formulas of Ref. 1 in our opinion contain some typos that we corrected below).
