Orbital angular momentum (OAM) signal mode crosstalk and energy loss induced by atmospheric turbulence are challenging phenomena commonly occurring in high-capacity and high-speed OAM-based free-space ...

We present a novel continuous-aperture orbital angular momentum (CAP-OAM) communication system, which can be regarded as an asymptotic generalization of existing (discrete) uniform circular ...
