Why are Stealth aircraft invisible to enemy radar?

Stealth aircraft are not actually invisible to radar, but the waves reflected by it are far fewer than what is needed for identification as a plane.

1) The first way that it prevents this is by its shape, which reflects radar waves in random directions, rather than back to the receiver.

2) Secondly, the special paint used has the ability to absorb electromagnetic energy in the same frequency as radar impulses.

3) Finally, the mission profiles often allow stealth aircraft to fly close to the ground, where their radar return can be lost in ground clutter.
