Could a maser be used to send information

  1. Sep 18, 2014 #1
    Just a quick question could a maser be used to send information from one point to another without detection ?

    Perhaps if there was a vacuum between the two points. But otherwise some microwaves would scatter and be detectable. It would be quite resistant to detection, but not foolproof.
