Re: [問題] 相厚度
※ 引述《applecatdog (阿伶)》之銘言：
: 抱歉,最近在看薄膜光學的書,想請教有一個名詞
: 叫"相厚度"會等於一個式子,我可以請問大家這
: 名詞是什麼意思?(網路我沒找到...)
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,我想請問如果用matlab寫有關薄膜光學的
: 程式(ex:算厚度,折射率...)會很困難嗎?
: 感謝大家的回覆!!
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. (not sure about the copyright)
