coupled modes
In fiber optics, a mode that shares energy among one or more other modes, all of which propagate together. [After 2196] Note: The distribution of energy among the coupled modes changes with propagation distance. 2. In microwave transmission, a condition where energy is transferred from the fundamental mode to higher order modes. Note: Energy transferred to coupled modes is undesirable in usual microwave transmission in a waveguide.
