Abstract
A novel approach for systematically deriving the complex poles and residues of a structure from a set of time-domain data is presented. The method is based on Prony\´s algorithm which involves the inversion of two matrices and a solution of the zeros of an 
th degree polynomial, being the number of desired poles. Two numerical examples are presented and several numerical advantages of this method are discussed.
