Do materials exist that (significantly) reflect one polarisation of light and transmit all others?

  • $\begingroup$ Depending on the application that you have in mind Brewster's Angle may be of interest to you. If, however, you are interested in a more general behavior then I have no suggestions. $\endgroup$ Apr 5, 2016 at 19:35
  • $\begingroup$ What do you mean by 'reflect on polarization and transmit all others'? In linearly polarized light, if you reflect one, there is only one other polarization to consider. $\endgroup$

    $\begingroup$ Such materials can be constructed, and are used to create modern polarizing beam splitters. $\endgroup$ Apr 5, 2016 at 21:03

1 Answer 1


Every material. Well, at a certain angle, at least (the Brewster angle), where p-polarized light is not reflected and hence only s-polarized light is reflected.

There is a modern interest in optical metamaterials and such things to engineer polarization reflections over wider angle ranges, though they tend to be limited in frequency.
