We present a metal–dielectric stack ultraviolet (UV) bandpass filter that rejects the longer wavelength, visible spectrum and is thin and relatively insensitive to the angle of incidence. Parametric evaluations of the reflection phase shift at the metal–dielectric interface provide insight and design information. This nontrivial phase shift allows coupled Fabry–Perot resonances with subwavelength dielectric film thickness. Furthermore, the total phase shift, with contributions from wave propagation and nontrivial reflection phase shift, is insensitive to the angle of incidence. Filter passbands in the UV can be shifted to visible or longer wavelengths by engineering the dielectric thickness and selecting a metal with an appropriate plasma frequency.

I'm trying to understand Brewster's angle and am stuck on what the different types of polarization actually mean (I'm a total beginner in physics so I might have misunderstood some very basic concepts).

In your example of light polarised at 45 degrees to the plane of incidence, then it is an an equal, in-phase mixture of s- and p-polarised light. You can calculate how each of these components behaves at the interface and then add together the resulting reflected and transmitted components to see what has happened to the reflected and transmitted light.

Electric polarization

Circularly polarized light

In the case of incidence at the Brewster angle, the reflection coefficient for the p-polarised light will be zero and the reflected light will contain only an s-polarised component. There is however a non-zero transmission coefficient for the p-polarised component.

What happens to that other light when interacting with a surface, or passing through a polarizing filter? From my reading so far it seems that there is a mathematical way to reduce these other orientations to combinations of s- or p-polarized light. How does that work? For example, if the electric fields of a light ray are at an angle of 45 degrees from the incident plane, does half of it behave like p- and half like s-polarized light? In the case of Brewster's angle, would that ray be half-transmitted and half-reflected, or only transmitted?

Unpolarised light would be modelled as an equal mixture of p- and s-polarised light with random, rapidly varying phase differences between them.

Any polarisation state for the incident light can be made up of a mixture of two polarisation states that are mutually perpendicular. Since you are free to choose these perpendicular directions (so long as they are also perpendicular to the wave-vector for transverse waves), it makes sense to have them parallel (p) or perpendicular (s) to the plane of incidence.

If your light is made up of a combination of s- and p-polarised light, then you treat each of these components separately and then add them back together when considering the reflected and transmitted light.

My textbook describes light as either $s$- or $p$-polarized or a mixture of both, depending on the orientation of the electric fields towards the plane of incidence. But the non-polarized incident light must also contain other types, that are not either perpendicular or parallel to the plane of incidence? Why do all the diagrams describing Brewster's angle only show two types of polarization then? Example, this diagram from Wikipedia:

2022516 — The design could focus nearly 98 percent of the rays generated by the lamps, producing a beam that could be seen more than 32 kilometers away.
