Phase plus Antiphase radio waves

  1. Jan 3, 2016 #1
    If you produced a focused beam from, say, a cassegrain transmitter which consisted of two waves merged but one inverted what would be the result. I presume there would be destructive interference.
    My question is, where does the energy go?

    The energy goes to the regions where the interference is constructive. In other words, you can't get a purely destructive interference everywhere.
