Design of acoustic metamaterials made of Helmholtz resonators for perfect absorption by using the complex frequency plane

In this review, we present the results on sub-wavelength perfect acoustic absorption using acoustic metamaterials made of Helmholtz resonators with different setups. Low frequency perfect absorption requires to increase the number of states at low frequencies and finding the good conditions for impe...
