This paper introduces a micro-lattice based metamaterial for low frequencywide-band vibration attenuation, that is enabled by engineering themetamaterial's building blocks to induce local resonance bandgaps for elasticwaves in all directions of propagation. The transmission rate through theproposed structure is examined and strong wave attenuation is demonstrated fora remarkably small number of unit cells. Additionally, it is shown that thebandgaps are tailorable via the geometrical parameters and can be leveraged todesign a hybrid metamaterial with an extremely wide bandgap. Alongside beingthin, lightweight, and capable of attenuating elastic waves in all directions,the proposed material also possesses the second order functionality ofexhibiting a negative Poisson's ratio and can pave the way for identifyingexotic functional materials.
