Data for publication: Studying the elastic wave mode propagation in D-shaped optical fibers

Dataset for publication: Studying the elastic wave mode propagation in D-shaped optical fibers. Image files from SEM in PNG format, and other files in txt format frorecreation of figures. The research was supported by the project titled: Guided waves based reference-free structural health monitoring using fiber Bragg grating sensors (2020/39/D/ST8/00188) granted by National Science Center, Poland. The authors are also grateful to TASK-CI for allowing the use of their computational resources.
