I would like to know the physical camera's sensor height. I'm not sure if the sensor's aspect ratio is 3/2, like a 35 mm, and also if this aspect ratio is maintained when the sensor width changes.

The official documentation states that you must adjust the sensor width in order to switch from a 35 mm to another type. However, how is this done when other sensors, such as the 4/3, have different aspect ratios ?

Thank you.

It is whatever it can be set to.

Camera sensors typically stick with a conventional width and custom height (not only referring to still cameras but also motion picture)

Since it is a virtual sensor / lens, the resolution can be locked into an aspect ratio and change to any desired value proportionally.

By default, it's a "35mm full frame" on a 50mm lens (at least in standalone) on a power-of-two resolution (1024x512) which when divided equals 2 (2:1 aspect ratio).

Available (primary) controls are:
- sensor width 

is mainly associated with the lens focal length and can be utilized as a crop factor (does not affect the aspect ratio)
- "image aspect ratio"
called "Film Settings" in Octane, where resolution of X and Y is set and consequently the aspect ratio of the image
- pixel aspect ratio (≠ aperture aspect ratio) 

only affects the pixels (e.g. squeeze/desqueeze anamorphic method), rarely ever changed even for "anamorphic looks"
