Longitudional electro magnetic waves and linear polarisation

  1. Oct 28, 2012 #1
    Hello,
    Are longitudinal EM waves ( I know they exist) any different from linearly polarised waves we learn about in antennae theory

    Just to be clear http://www.antenna-theory.com/basics/polarization.php defines linear polarisation pretty clearly in the context i am talking about

    yes.

    As your link indicates, polarized waves are transverse waves', Longitudional waves are not. EM waves are transverse except under special constraints:
