Abstract

In this work we study the optical response of Kretschmann-ATR structures with metamaterials near conditions of resonant coupling between the incident wave and a surface plasmon polariton. In contrast with previous research available in the literature, particular attention is paid to the behavior of the phase of the reflected fields. Besides, the results are discussed in the frame of a phenomenological model based on the properties of the complex poles and zeroes of the reflection coefficient.
