No, they do NOT.
What waves need to propagate is this and ONLY this:
That the laws that govern the physical entities involved take the form
of a differential equation known as the wave equation.
Yes, waves do require a medium in order to propagate.
A wave cannot propagate through a void.
More with the equations.
*How* does a wave propagate through a void?
