A Unique Extraction of Metamaterial Parameters Based on Kramers-Kronig Relationship

In this paper, an improved algorithm for extracting the effective constitutive parameters of a metamaterial is derived. The procedure invokes the Kramers-Kronig relations to ensure the uniqueness of the solution. The accuracy of the method is demonstrated by retrieving the effective material paramet...
