Direction and polarization of the plane wave #21

Closed 1br14n closed 4 years ago

1br14n commented 4 years ago

Hi! I'm having a bit of trouble to understand the incident field, hope you can help.

If (0,0,0) means a z-directed, x-polarized plane wave, does ( pi/2, 0, pi/2 ) means a x-directed, y-polarized p. w. and ( pi/2, pi/2, 0) y-directed, z-polarized p. w. ?

I'm confused since azimuth is usually measured from the +z axis, and the polar in the xy-plane, but I have none experience with Euler's angles.

Thank you in advance

Hi

You can find all the information you need in my Ph.D thesis at page 4.

Thank you, that's exactly what I was looking for. Your comment in pages 38-39 about S. et al claims was very interesting.

You mention using non polarized light for the when working with nano-planets. How do you set the light as non-polarized? I could no find any clue in the examples.

Greetings!

Hi

Regarding your comment on non polarized light I am non really sure about how I did it at the time. I must have done it numerically by averaging the cross sections of several different illumination polarizations. Unfortunately 13 years are a long time and at the time a was less strict in term of data storage and code versioning.

I am instead absolutely sure about the comments on pg 38-39. Take a look at this publication if you are interested.
