Can Electron waves undergo Polarisation just like Light? Here electron waves refers to the matter wave of electrons as proposed by De-Broglie hypothesis.
 A: Yes. Photon spin is a two-state system, and optical polarization is directly related to coherent photon spins. Electron spin is also a two-state system, and so much of the math for describing polarized electron beams is the same as for polarized photon beams.
The analogy is not perfect. The photon is a  spin-one system which follows the two-state algebra because the spin-zero projection is forbidden. A photon beam with spin axis parallel to its momentum is circularly polarized. Linear-polarized light is a coherent mixture of left- and right-circular polarizations, with the polarization direction determined by the relative phase. But there is no way to produce "up-polarized" light: the orthogonal bases are vertical/horizontal and diagonal/diagonal.
For an electron beam,  however, you can point the spin axis in any direction in space. There is no way to make a "plane-polarized" electron beam; electrons polarized so their north poles point "up" are orthogonal to electrons whose north poles point "down."
A: I don't know about "all properties of em waves", but electron spin (projection) is at least an analog of light polarization, and spin projection is a property of electron waves.
