Meta Materials as Cosmic Ray Shielding for Spacecraft?

  1. Dec 7, 2013 #1
    While thinking about the recent-ish developments in meta materials for 'cloaking' systems, a thought struck me: could a meta material or combination of meta materials (probably of a somewhat more advanced state than they currently are) be used as a form of shielding from cosmic rays of various kinds for a spacecraft travelling to other planets in our solar system?

    Meta does not mean magic. They would do no better - and no worse - than ordinary materials in this regard.

    Since cosmic rays are high energy charged particles, the walls of a spacecraft will suffice. The cloaking system is designed to affect electromagnetic radiation - no effect on charged particles other than as matter itself.

    So for basic particles, no use. What about solar radiation?
