Experimental investigation of seismic metamaterials

----- The META-WT project is built on a 3-weeks seismic experiment in Germany with a dense seismic array of 400 three-component geophones that will cover (1) a 2.5 km x 2.5 km wind farm with almost 200 wind turbines (WTs) and (2) a 20-km long radial line from the center of the wind farm to the north with one geophone every 0. 75 km. New sensing technologies (fiber optic cable (DAS), rotation sensors, and Lidar vibrometer) will be used as complementary components for obtaining (3) highly (…)

Towards Seismic Metamaterials: From Forests to Wind Farms to Cities

Phd manuscript of Shoaib Ayjaz MOHAMMED Phd defense scheduled on Sept. 26th, 2024
Abstract
It is well established that the presence of the urban agglomerate significantly modifies the free-field ground motion at the city scale. Each building can behave as a resonator, trapping a small fraction of seismic surface waves that is reradiated into the ground. But when tall buildings are densely clustered, like in a city, can we anticipate surface waves to interact with them in unusual ways? (…)
