Abstract
This article aims to study the interaction of Rayleigh or surface wave with a varying angled wedge using numerical simulations. This work uses numerical tools to understand this complex problem and fills some existing gaps such as the influence of frequency and geometry of the wedge (curved vs. sharp transition). Quantitative analysis was carried out by calculating the transmission and reflection coefficients, and qualitative analysis used displacement vector plots to study the scattering and mode conversion phenomenon. The results suggest a strong dependence of transmission and reflection coefficients on the frequency and geometry of transition, which has not been reported before in the literature.
期刊介绍：
Acta Acustica, the Journal of the European Acoustics Association (EAA).
After the publication of its Journal Acta Acustica from 1993 to 1995, the EAA published Acta Acustica united with Acustica from 1996 to 2019. From 2020, the EAA decided to publish a journal in full Open Access. See Article Processing charges.
Acta Acustica reports on original scientific research in acoustics and on engineering applications. The journal considers review papers, scientific papers, technical and applied papers, short communications, letters to the editor. From time to time, special issues and review articles are also published. For book reviews or doctoral thesis abstracts, please contact the Editor in Chief.
