Abstract: Large‐aperture antenna arrays promise fine angular resolution, but their dense layouts usually lead to prohibitive cost and design complexity. Sparse arrays present a compelling alternative, ...
The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...
