Figure 8

Simulated total received power and received power of p = 0, p from 0 to 10, p from 0 to 20, and all p modes from (a) the direct path, (b) the reflected path of the Gaussian (ℓ = 0) beam, and (c) the direct path, (d) the reflected path of OAM + 3 beam at different propagation distances. The inset in (a) shows a zoomed figure of the receiver power with a propagation distance from 40 to 60 m.
