Green's Function Approach to Model Vibrations of Beams with Spatiotemporally Modulated Properties
Benjamin M. Goldsberry, Andrew N. Norris, Samuel P. Wallen +1
The forced time harmonic response of a spatiotemporally-modulated elastic beam of finite length with light damping is derived using a novel Green's function approach. Closed-form s…

Nonreciprocity and mode conversion in a spatiotemporally modulated elastic wave circulator
Benjamin M. Goldsberry, Samuel P. Wallen, Michael R. Haberman
Acoustic and elastic metamaterials with time- and space-dependent material properties have received great attention recently as a means to break reciprocity for propagating mechani…
