The operator calculation of Helmholtz equation?
I am reading the beam propagation method (BPM) in optical imaging paper. I find a paper solve the Helmholtz equation in the inhomogeneous media. The paper is:
Light propagation in graded-index optical ...

EM wavelength in different medium
Considering a light wave traveling from the vacuum to air, I am trying to find what will happen to its wavelength.
At first, using optics, we know that:
$$n=\frac{c}{v}$$
where $n$ represents the ...

Reflection and transmission coefficients
Suppose we have a plane wave with s-polarization travelling through a medium with refractive index $n_1$ in direction $\vec{k}$ perpendicular to a surface of a dieletric with refractive index $n_2$; ...
