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…
Beating resonance patterns and extreme power flux skewing in anisotropic elastic plates
Daniel A. Kiefer, Sylvain Mezil, Claire Prada
Elastic waves in anisotropic media can exhibit a power flux that is not collinear with the wave vector. This has notable consequences for waves guided in a plate. Through laser-ult…
Computing zero-group-velocity points in anisotropic elastic waveguides: Globally and locally convergent methods
Daniel A. Kiefer, Bor Plestenjak, Hauke Gravenkamp +1
Dispersion curves of elastic waveguides exhibit points where the group velocity vanishes while the wavenumber remains finite. These are the so-called zero-group-velocity (ZGV) poin…
