Yeah, there aren't enough details here to prove the claims. Not to mention, how much power do the "transmitting relays" use. Those sound like they need to be active devices that require a power source. Yes you can siphon off power from the beam, but with all the losses involved it doesn't seem to make sense.
Does this mean that the meta-material lenses are custom built for each relay station? For example, to bend the beam around fixed obstacles like a mountain. Do you believe this will be a barrier to manufacturing and installation?
Or are you creating a generic lens that is factory tuneable to the needed characteristics?
