Figure Lengend Snippet: Comparison of the experimental and numerical displacement transmittance response for the uniform metabeams based on tacticity. The primary beam has 11 secondary beams embedded uniformly at a fixed distance from each other. The secondary beams at both tips have equal end masses to design the isotactic metabeams having uniform configurations as shown in ( a ) Isotactic symmetric array in which end mass distribution of 2m–2m and m–m is followed about the mid highlighted secondary beam on both sides. ( b ) Isotactic anti-symmetric array in which end mass distribution of 2m–2m and m–m on the secondary beams is followed on the first half of the metabeam and opposite mass distribution is present on the second half of metabeam.

Article Snippet: The experimental results obtained for the fabricated metabeams are also well validated with finite element numerical models of metabeams in COMSOL Multiphysics.

Figure Lengend Snippet: Comparison of the experimental and numerical displacement transmittance response for the uniform metabeam based on tacticity. The primary beam has 11 secondary beams embedded uniformly at a fixed distance from each other. The secondary beams at both tips have unequal end masses to design the metabeams based on tacticity having uniform configurations as shown in ( a ) Syndiotactic symmetric array in which end mass distribution of 2m–m and m–2m is followed about the mid highlighted secondary beam. ( b ) Isotactic array in which end mass distribution of 2m–m is shown on the entire beam. ( c ) Syndiotactic array in which end mass distribution of 2m–m on the first half and m–2m on another half about the highlighted secondary beam. ( d ) Syndiotactic array in which end mass distribution of 2m–m and m–2m is shown on the first half of the metabeam about the highlighted secondary beam. The other half of the metabeam is isotactic and has an end mass distribution of m–m and 2m–2m .

Figure Lengend Snippet: Comparison of the experimental and numerical displacement transmittance response for the non-uniform metabeam based on tacticity. The primary beam has 11 secondary beams embedded non-uniformly at varying distances from each other. The secondary beams at both tips have equal end masses to design the isotactic metabeams having non-uniform configurations as shown in ( a ) Isotactic symmetric array in which end mass distribution of 2m–2m and m–m is followed about the mid highlighted secondary beam on both sides.
