    Description

    Linear geometrical optics
    describe the propagation of
    waves with high frequency as
    the propagations of rays and
    supplies an approximate
    solution. The approximate
    solution is considerably
    easier to evaluate
    numerically, than the
    actual solution to the
    partial differential
    equation. For nonlinear
    phenomena there exists a
    number of studies and
    heuristics, while the
    development of a stringent
    theory is still only
    commencing. For instance,
    the exponential functions
    in the linear approximation
    need to be replaced by more
    general 'profiles' in order
    to take the creation of
    harmonics into account.
