本研究探討金屬表面受入射電磁波所產生之表面電漿之熱流效應。鎔區受熱毛細力與表面張力所驅動之效應。表面電漿是金屬內部之自由電子受到外加電磁場作用所產生集體震盪之行為。電磁波因屏蔽效應無法穿透金屬，因此被侷限在金屬表面。此電磁波所產生之介電、磁及電阻損失加熱金屬表面，以進一步探討熱毛細力與表面張力對金屬鎔區內之效應。本研究使用COMSOL 軟體以頻域有限差分法( finite difference frequency domain method)求解馬克斯威爾方程式、質量守恆、動量以及能量方程式，以探討電磁波對材料表面加熱時之效應。

This study investigates the effect of thermocapillary and surface tension forces on thermal phenomena in metal, heated by surface plasmon induced by incident electromagnetic wave. Surface plasmon wave is a consequence of the collective oscillation behavior of free electrons within the metal excited by external electromagnetic field. In view of the shielding effect of high electron density in metal, the electron waves cannot penetrate the metals, but generate a confined longitudinal wave on the surface.
Electromagnetic wave generate dielectric、magnetic and resistance lose to heat the surface. We study further the effect of thermocapillary and surface tension on the flow in molten field. In this study, Maxwell's equations、momentum equation、energy equation are solved from COMSOL software.
