We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structure which is fabricated out of porous ...
[EN] Topological phases have recently been realized in bosonic systems. The associated boundary modes between regions of distinct topology have been used to demonstrate robust waveguiding, protected from defects by the ...
[EN] The closed form expressions of the effective properties in periodic fluid laminates are derived thanks to the Pade approximation of the transfer matrix. A second-order Taylor expansion of the transfer matrix elements ...
