I read the article in New Scientist this morning and it sounds like sound physics being used to tackle a serious problem for interplanetary space travel. Well worth a read. It would be used in combination with physical shielding as it only works against charged particles while neutral ones would get past the magnets. The original idea is quite old but was discounted because the original maths didn't take into account the effect of particles repelling each other as well as the magnets.
