  • Patent number: 11781614
    Abstract: Described is a system for transmitting a flexural wave acting on one structure to another structure. In one example, a system includes a first structure having a first property and a first end and a second structure having a second property and a second end connected to the first end of the first structure. The first property is different from the second property and may be related to the material and/or geometric properties of the first and second structures. A mechanical resonator is connected to the first structure at a distance from the first end of about a quarter-wavelength of the frequency of a flexural wave acting on the first structure. The mechanical resonator matches a first mechanical impedance of the first structure to a second mechanical impedance of the second structure to allow high transmission of the flexural wave acting on the first structure to the second structure.
