Webb6 juni 2024 · That's a very rough way of understanding it. A better way to describe it is that a mode is a way for the EM field to satisfy the boundary conditions imposed by the physical structure of the fiber, such that the field patterns at different positions along the fiber's length remain the same. If light propagates in an Optical fiber in a single ... WebbThe geometrical theory of diffraction (GTD) extends the idea of rays by introducing the concept of diffracted rays that differ from the rays of geometrical optics in that these are produced when a ray (which may, in certain cases, be a diffracted ray itself) hits an edge or a corner of an obstacle, or grazes the surface of the obstacle. All these cases are …
