Chiral metamaterials provide a very convenient way to actively regulate the light field via external means, which is very important in nanophotonics. Howev... Z Chen,S Chen,Y Wang,... - 《Nanophotonics》 被引量: 0发表: 2019年 Programmable gear-based mechanical metamaterials A design paradigm ...
Further, mechanical metamaterials based on double-layers planetary gear (DLPG) train and Ravigneaux planetary gear (RPG) train are designed. The compressive elastic modulus, shear modulus, and amplitude-frequency response are calculated and investigated with finite element simulation. The results, with ...
