Sci. 2025, 15, 858.https://hdl.handle.net/10919/124346Two complicating features commonly found in wave propagation applications include dispersion, i.e., frequency-dependent propagation velocity, and reflections, which introduce coherent noise. In this work, we present a signal processing technique which can be applied in a variety of applications to decompose signals into their forward- and backward-propagating components. The theory is presented, along with algorithmic implementation and experimental validation on a Timoshenko beam. The implications and potential utility of the method are briefly discussed.enCreative Commons Attribution 4.0 InternationalArticle - Refereed2025-01-24https://doi.org/10.3390/app15020858
