Scattering of the metacity cloak by a plane wave source at 40 Hz with different materials in (A) and (B): (A) concrete buildings on a concrete plate (E = 25e9 [Pa], ρ = 2300 [kg/m³], ν = 0.2); (B) consists of steel (E = 200e9 [Pa], ρ = 7870 [kg/m³], ν = 0.29) buildings on a concrete plate (right panel). Lower panel (C) is a 3D view of (B) Profile of magnitude of total displacement field integrated along the red segment in (A) and (B) suggests reduction of total displacement by up to 10% in the core of seismic cloak in (A) and reduction of total displacement by up to 80% in the core of seismic cloak as well as behind it in (B).
