  The dynamical percolation transition of two dimensional Axial Next Nearest
Neighbour Ising (ANNNI) model to pulsed magnetic field has been studied by
finite size scaling analysis (by Monte Carlo simulation) for various values of
frustration parameters, pulse width and temperature (below the corresponding
static transition temperature). It has been found that the size of the largest
geometrical cluster shows a transition for a critical field amplitude. Although
the transition points shift, the critical exponents remain invariant for a wide
range of frustration parameters. It is also same as that obtained for the 2d
Ising model. This suggests that although the static phase diagrams of these two
models differ significantly in various aspects, the dynamical percolation
transition of both these models belong to the same universality class.
