※ 引述《applecatdog (阿伶)》之铭言： : 抱歉,最近在看薄膜光学的书,想请教有一个名词 : 叫"相厚度"会等於一个式子,我可以请问大家这 : 名词是什麽意思?(网路我没找到...) For the wave propagating along z direction, most of the textbook describes it in a complex form (time-independent) as E(z)=E(0)exp(-jkz). Here, k=2nπ/λ is the propagation constant and z is the distance. n and λ are, respectively, refractive index and free-space wavelength. Some texbooks, especially regarding topics of "thin-film," define β=kz as phase thickness. Thus, the wave equation is expressed as E(z)=E(0)exp(-jβ). Via introducing phase thickness, β, the wave propagation matrix (usally very messy in mutil-layer) looks more clear and explicit. : 另外,我想请问如果用matlab写有关薄膜光学的 : 程式(ex:算厚度,折射率...)会很困难吗? : 感谢大家的回覆!! If you never use MatLab, I recommend a book "Engineering Optics With Matlab" It only has 260 pages. http://www.amazon.com/Engineering-Optics-Matlab-Ting-Chung-Poon/dp/9812568735 Or you can find pdf edition online.
