  The dynamical responses of a ferromagnetic film to a propagating spherical
electromagnetic wave passing through it are studied by Monte Carlo simulation
of two dimensional Ising ferromagnet. For a fixed set of values of the
frequency and wavelength of the spherical EM wave, and depending on the values
of amplitude of the EM wave and temperature of the system, three different
modes are identified. The static pinned mode, the localised dynamical breathing
mode and extended dynamical spreading mode are observed. The nonequilibrium
dynamical-symmetry-breaking breathing and spreading phase transitions are also
observed and the transition temperatures are obtained as functions of the
amplitude of the magnetic field of EM wave. A comprehensive phase diagram is
drawn. The boundaries of breathing and spreading transitions merge eventually
at the equilibrium transition temperature for two dimensional Ising ferromagnet
as the value of the amplitude of the magnetic field becomes vanishingly small.
