WAVEWATCH III ® (Tolman 1997, 1999a, 2009) is a third generation wave model developed at NOAA/NCEP in the spirit of the WAM model (WAMDIG 1988, Komen et al. PDF | Presently, the propagation of electromagnetic waves in photonic crystals has become the subject of extensive research due to its remarkable properties.
