    Yes, you are not the first one with this question on this forum and no, even for you physics applies the same. Once you radiate something you cannot say "and my waves will be magically cut exactly at 2 meters from my device";) The only thing you can do is design such "bad" antenna that signal will get below usual sensitivity levels at that distance. But because wide variance on receivers' side (some can detect signal at -80dBm, some go as low as -98dBm or even lower) you will hardly succeed.
