I wonder if this has wireless security applications along the lines of this paper: https://dl.acm.org/doi/pdf/10.1145/3300061.3300120 https://dl.acm.org/doi/pdf/10.1145/3300061.3300120 Possibly the reduced far field radiation could enhance the security, kind of a "cone of silence" for radio, making long distance attacks even less likely.
