Molten region growth on an array of
cylinders on metal surface subject to a
pulsed laser beam

This study numerically investigates heating and melting
of different arrays of cylinders on a metal surface
subject to an electromagnetic wave or laser beam in a
TM mode. The TM mode represents magnetic field to
be perpendicular to the incident plane of electrical field.
A systematical investigation of heating and melting of an
array of nanoparticles on a surface is essentially required
to understand 3-D printing and different types of plasma
processing and nanotechnology. The results show that
electromagnetic wave propagating along the boundary
between two media leads to a distributed energy input
on the surface of the array. Free surface deformation of
molten pool required more systematical understanding of
complicated transport phenomena.
