Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

People and Nature, EarlyView.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.
