本論文探討奈米尺寸之金屬顆粒受到TM波加熱之熔化過程。TM波代表電磁波傳播方向無磁場分量，磁場垂直於傳播方向的平面。TM波正上方入射至金屬顆粒。金屬顆粒在極短的時間內快速熔化，液體金屬受到外力(熱毛細力、表面張力和勞倫茲力)產生流動。本研究探討不同的作用力對奈米級的金屬顆粒熔化過程之影響。

本研究採用模擬軟體COMSOL Multiphysics求解統御方程式包含相位場、電磁波、質量、動量和能量方程式。

This study investigates the melting of nano-sized metal particles heating by TM wave. The TM wave represents the magnetic field is perpendicular to the incident plane containing electric field. The incident TM wave from the top to the metal particles melt rapidly in a very short time. Liquid metal began to flow as result of driving by external forces (Thermocapillary force, Surface tension and Lorentz force).This study investigates the effect of different external forces on the melting of metal particles in nanoscale.

This study use the software "COMSOL Multiphysics" to solve the governing equations include phase-field equation, electromagnetic wave equation, mass equation, momentum equation and energy equation.
