Experimental Investigation on Degradation of an Orbital- Angular-Momentum Beam Passing Through Dynamic Aerosol and Air-Water Interface for Air-to-Water Communications

We experimentally investigate the degradation of a data-carrying OAM beam passing through dynamic aerosol and non-planar air-water interface and observe an up to -6.5-dB modal crosstalk from OAM -1 to OAM +1 under the effects.
