Abstract: A new two-dimensional spatial spectral estimation direction finding method based on L-shaped array and time modulation theory is proposed. The main principle of this method is to generate a ...

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...

Abstract: The classical sparsity-based source identification method encounters the basis mismatch problem due to discretizing the focus region and assuming that acoustic sources are on-grid. This ...
