Extreme wave skewing and dispersion spectra of anisotropic elastic plates
Daniel A. Kiefer, Sylvain Mezil, Claire Prada
Guided wave dispersion is commonly assessed by Fourier analysis of the field along a line, resulting in frequency-wavenumber dispersion curves. In anisotropic plates, a point sourc…

Notes on osculations and mode tracing in semi-analytical waveguide modeling
Hauke Gravenkamp, Bor Plestenjak, Daniel A. Kiefer
The dispersion curves of (elastic) waveguides frequently exhibit crossings and osculations (also known as veering, repulsion, or avoided crossing). Osculations are regions in the d…
