 ve attenuation over long distances - Malte Peter (Universität Augsburg)

DESCRIPTION:Ocean surface waves attenuate with distance travelled into the
  sea-ice covered ocean. This is reminiscent of the wave localisation pheno
 menon\, which occurs in many branches of wave science. For an incident wav
 e train propagating into a rough (randomly disordered) medium\, wave local
 isation refers to exponential attenuation (on average) of the wave train i
 n the rough medium. This talk is motivated by seeking efficient ways to ca
 lculate the attenuation rate as a function of the incident wave properties
  (frequency) and the properties of the given medium\, including the statis
 tical properties of the disorder. Effective media theory is an appealing w
 ay to approach the problem\, as it provides analytical insight\, circumven
 ting the need to compute individual wave fields repeatedly for different r
 ealisations of the disorder\, as well providing the opportunity for elegan
 t mathematical analysis. I will present the theory alongside corresponding
  results and discuss the applicability of effective media theory for makin
 g predictions of wave attenuation over long distances.  &nbsp\;  This is j
 oint work with L. G. Bennetts (Adelaide) and S. Rupprecht (Augsburg).  <br
