On the applicability of Kramers-Kronig dispersion relations to guided and surface waves
Victor V. Krylov
In unbounded media, the acoustic attenuation as function of frequency is related to the frequency-dependent sound velocity (dispersion) via Kramers-Kronig dispersion relations. The…

Localised flexural waves in wedges of power-law profile and their relationship with acoustic black holes
Victor V. Krylov
In the present paper, the relationship between localised flexural waves in wedges of power-law profile and flexural wave reflection from acoustic black holes is examined. The geome…
