Abstract

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.
