The radar principle of nature, returns every action to the focal point of its own source from every direction of its source. The video is showing this principle in a rectangular room with a central source. If you start with a square room, you will create the perfect conditions for the formation of a sun... At the end of the video is shown how several source are placed in different rooms and activated at the same time. They all work together as One. Also notice how none of the waves are actually leaving the rooms (just reversing polarity) although it looks like they are going through the walls.
