Electromagnetic waves traveling through a mesh

  1. Nov 25, 2011 #1
    You know how a microwave oven has a mesh on the door so visible light gets through but not the microwaves? Can such a thing be done with infrared radiation too? Is it possible to block heat from getting through a mesh but not visible light?
