Dominant mode upslope propagation inside a non-penetrable wedgewaveguide (Modal intensity vs. range-cross-range)
Source publication
This presentation is intended to tutorially enhance the utility and understanding of the analytical and numerical representations for the wave propagation problem inside a wedge-waveguide with both non-penetrable and penetrable boundaries; through visualizations of the dynamical interaction between the various wave species, implemented through educ...

... in Cartesian Coordinates. The interesting case is the upslope propagation where wave fields travel in the direction of narrowing waveguide cross-section up to the cut-off (caustic) transition region, converting the incoming waves into reflected and evanescent fields on the propagating and non-propagating sides, respectively, of the caustic (see Fig. 2 for the lowest order mode). For the penetrable wedge- waveguide case, the upslope propagating wave fields leak (penetrate) outside the wedge-waveguide as reached wave (modal) caustics. ...
