AbstractRETRACTION: Ijaz, Q., Bourennane, E.‐B., “An improved hybrid network‐on‐chip with flexible topology and frugal routing”, The Journal of Engineering. e12395 (2024). https://doi.org/10.1049/tje2.12395The above article, published online on 11th June 2024 in Wiley Online Library (wileyonlinelibrary.com) has been retracted by agreement between the journal's Editor‐in‐Chief, James Lam; the Institution of Engineering and Technology; John Wiley & Sons Ltd and the authors of the article.The authors contacted the journal and stated that the following parts of the paper had been inadvertently reproduced from a source [1] without appropriate permission or acknowledgement: FIGURE 3 Architecture of RF interface, in the paper, is taken from, Figure 4.2—Schéma fonctionnel de l'Interface RF of the thesis (page no 63). FIGURE 4 Digital waveguide: An abstraction of five components is taken from Figure 5.1—Modèle de l'interface RF of the thesis (page no 84). Tables 1–3 are tables 6.4–6.6 of the thesis (page no 108–109). Tables 4–6 are tables 6.8–6.10 of the thesis (page no 111–112). The decision for retraction was taken as these unauthorized data are essential to support the conclusions of this manuscript.REFERENCES[1] Brière, A.: Modélisation système d'une architecture d'interconnexion RF reconfigurable pour les many‐cœurs.
