Orthogonality means one mode's excitation cannot be created by combining other modes. If the orthogonality of the modes is perturbed, inter-mode interference (IMI) occurs between the OAM modes.

OAM-based communication offers the potential to use orthogonal modes as separate communication channels, but certain environments limit this potential by introducing IMI. It is, therefore, advantageous to investigate the conditions under which IMI occurs.
