Maybe you aren't displacing matter at all, just converting a bit of air into your body with some subatomic rearrangement.  There would be a slight vacuum towards your body when you arrived (since air isn't a particularly dense form of matter) and a slight pulse of wind where you left as what was your body gets turned back into air.  If the signal that is transmitting your form is something that follows normal physics like the speed of light, perhaps the energy differential is dissipated over the space in between the two points.  Could you stop someone from teleporting with a Faraday Cage?
