I don't know where you got that idea. I would assume they push light stuff away from the course of the ship. 

There is a similar thing in Weber's Honorverse - a shield designed to catch space dust that would damage the ship at high velocity.

I missed that. Means, the shield sees the particle and steers the 
ship around it? I'm not totally sure that would save energy relative 
to zapping the particle.
