발명의 명칭: (EN) ELASTIC MATERIAL FOR COUPLING TIME-VARYING VIBRO-ACOUSTIC FIELDS PROPAGATING THROUGH A MEDIUM
(FR) MATÉRIAU ÉLASTIQUE PERMETTANT DE COUPLER DES CHAMPS VIBRO-ACOUSTIQUES VARIANT DANS LE TEMPS ET SE PROPAGEANT À TRAVERS UN MILIEU
요약서:
(EN) A device for use in a medium comprising a medium vibro-acoustic impedance. The device includes an elastic material including a plurality of unit cells. The plurality of unit cells includes a first unit cell. The first unit cell includes a first unit-cell joint comprising a first unit-cell joint wall defining a first joint central void, a first unit-cell joint inclusion located in the first joint central void, and at least two first unit-cell arms connected to and extending away from the first unit-cell joint. The elastic material includes an elastic-material vibro-acoustic impedance. The elastic-material vibro-acoustic impedance and the medium vibro-acoustic impedance are sufficiently vibro-acoustically impedance-matched to couple time-varying, propagating vibro-acoustic fields between said elastic material and the medium.
(FR) L'invention concerne un dispositif destiné à être utilisé dans un milieu présentant une impédance vibro-acoustique. Le dispositif contient un matériau élastique comprenant une pluralité de cellules unitaires. La pluralité de cellules unitaires compte une première cellule unitaire. La première cellule unitaire contient un premier joint de cellule unitaire comportant une paroi de premier joint de cellule unitaire définissant un vide central de premier joint, une inclusion de premier joint de cellule unitaire située dans le vide central de premier joint et au moins deux bras de première cellule unitaire raccordés au premier joint de cellule unitaire et s'étendant à distance de ce dernier. Le matériau élastique présente une impédance vibro-acoustique. L'impédance vibro-acoustique du matériau élastique et l'impédance vibro-acoustique du milieu présentent une adaptation d'impédance vibro-acoustique suffisante pour coupler des champs vibro-acoustiques se propageant et variant dans le temps entre ledit matériau élastique et le milieu.
