We compare our analytical results with the dispersion relations extracted from the experimental measurements.http://www.sherpa.ac.uk/romeo/issn/0003-6951..."Publishers version/PDF may be used on author's personal website, institutional website or institutional repository" from SHERPA/RoMEO site (as at 23/09/15).
