大学物理教学中基于转移矩阵法的薄膜干涉探讨

转移矩阵法是研究介质膜或势垒中的光子或电子输运的一种理论计算方法。本文结合广泛用于光学传输的转移矩阵方法,对“大学物理”中的劈尖干涉和牛顿环现象进行了数值模拟。研究发现转移矩阵方法不仅可以解决接触面为平面的劈尖干涉,还可以解决接触面为曲面的牛顿环现象。此研究不仅可以辅助课堂教学加深学生对薄膜干涉问题的理解,还可以激发学生对于科研的热情,培养学生利用数值计算方法解决生活中的实际问题。

The transfer matrix method is a theoretical calculation method used to study the transport of photons or electrons in media films or potential barriers.This paper combines the widely used transfer matrix method in optical transmission to numerically simulate the phenomenon of sharpe interference and Newton's rings in"University Physics".The study found that the transfer matrix method can not only solve sharpe interference with a flat contact surface but also solve Newton's rings with a curved contact surface.This research not only assists classroom teaching in deepening students'understanding of thin film interference problems but also inspires students'enthusiasm for scientific research and cultivates their ability to use numerical calculation methods to solve practical problems in life.
