Microstructural topological sensitivities of the second-order macroscopic model for waves in periodic media
M Bonnet, R Cornaggia, BB Guzina - SIAM Journal on Applied Mathematics, 2018 - SIAM
We consider scalar waves in periodic media through the lens of a second-order effective, ie,
macroscopic description, and we aim to compute the sensitivities of the germane effective …
