Abstract : We present an original method devoted to the optimal identification of a wide class of complex linear operators involving some delay components, based on suitable infinitedimensional state formulations of diffusive type. Thanks to the intrinsic properties of these state formulations, cheap and precise numerical approximations are straightforwardly obtained, leading to approximate quadratic problems of reasonable dimension. We then propose this method for identification of the acoustic impedance of absorbent materials designed for noise reduction of aircraft motors
