description The invention belongs to the technical field of wireless communication, and discloses a vortex electromagnetic wave modal transformation apparatus. A vortex electromagnetic wave generation apparatus is positioned on one sides of metal plates of electromagnetic metasurface units, and is fixed on the central axis of the electromagnetic metasurface units through a bracket. Each electromagnetic metasurface unit disclosed in the invention consists of four metal plates which are stacked mutually and are not in contact; cross-shaped grooves in periodical distribution are etched in the metal plates; vortex electromagnetic wave can realize phase compensation through equivalent capacitance and inductance generated by mutual resonance between the cross-shaped grooves of each electromagnetic metasurface unit to further change the phase distribution on the vortex electromagnetic wave cross section and to complete vortex electromagnetic wave modal transformation; compared with the prior art, the vortex electromagnetic wave
