Homework Help: Using Optics To Make An Aircraft Invisible

  1. Oct 27, 2011 #1
    Using Optics To Make An Aircraft "Invisible"

    1. The problem statement, all variables and given/known data
    Does it seem possible (or practical) to make airplanes invisible to microwave radar by applying some kind of anti-reflection coating?


    2. Relevant equations



    3. The attempt at a solution
    I'm not sure what to say for this. I want to say that it is possible because it seems as if the government has such aircrafts, but I can't seem to think of a reason why. I thought about using Fresnel coefficient for reflection, but I got stuck. Thanks.

    I think you can just do some reading about "radar absorbing materials" to get some ideas....

    Hmm I tried to do that, but I couldn't really find any detailed explanation (in terms of Optics) of how they worked. I just found some results about aircrafts that used the technology.
