In quantum mechanics, matter-wave amplitude determines probability that particle is at that position. Matter waves are infinite and so have positive amplitude at all space points. Therefore, unlike classical mechanics, particles have a probability of being outside potential-energy barriers {tunneling}|.
At barriers, particle waves reflect back or refract through. Particles with higher matter-wave frequency and more energy have more refraction. As difference between barrier potential energy and particle energy increases, reflection {anti-tunneling} increases.
