title: Multimode waveguide: a low pass filter.
abstract: It is shown in this paper that a multimode waveguide-represented by a ray model-acts like a low-pass filter with respect to the modulation. The response function is calculated and discussed in the case of an ideal, straightlined, loss-free system.
