Explore how metamaterials are revolutionizing architecture with acoustic invisibility, earthquake resilience, and energy harvesting solutions.

The Physics of Sound: From Whale Songs to Invisibility Cloaks Blue whales communicate over 1,000 km via 188 dB songs (louder than a jet engine at 25m). Metamaterials bend sound waves around objects, ...

Abstract: The higher order multipoles above the electric quadrupole are commonly neglected in metamaterial homogenization. We show that they nevertheless can be significant when the second-order ...
