• Salami-type porous metal
• Glass microcapsule
• Attenuation characteristic
• Micro-bell structure

We used a new method to fabricate salami-type porous metal from glass microcapsules and liquid metal. Each pore of this salami-like structure behaves as a micro-bell. This metal, which is more than 20% lighter than bulk material, also shows a unique characteristic: high-frequency oscillation is greatly attenuated when propagated within it. This method offers great potential for size, shape and conformation control, with changes in the attenuation characteristics of the salami-like pore structure being achieved merely by altering the mixing technique.
