Probing or imaging an acoustic source in an acoustic scattering environment is a fundamental challenge in disordered systems theory 1,2,3,4 but highly desirable. It has many significant applications, ...
Multilayer thin film (MTF) filter arrays for computational spectroscopy are fabricated using stencil lithography. The MTF filter array is a 6 × 6 square grid, and 169 identical arrays are fabricated ...
