本研究探討材料表面因入射電磁波作用產生表面電漿之現象。表面電漿為一種存在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。由於金屬的電子密度極高會造成屏蔽效應，電磁波無法穿透，而形成被侷限在金屬表面之縱波。此縱波稱之為非輻射表面電漿。電磁波的計算是使用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。本研究探討電磁波的波長、入射角度，及不同材料光學性質對材料表面熱場之效應。

This study investigates phenomena of surface plasma induced by an incident electromagnetic wave on a surface. Surface plasmon wave is a consequence of the collective shock behavior of free electrons within the metal excited by external electromagnetic field. Owing to 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. This wave is called non-radiative surface plasmon waves. In this study, electromagnetic waves are obtained by solving Maxwell's equations from COMSOL software using the finite difference frequency domain method. The effects of wavelength and incidence angle of electromagnetic wave and optical properties of materials on thermal fields near a surface are presented.
