Abstract: This paper proposes two-dimensional (2D) sparse billboard and T-shaped arrays. The arrays have closed-form expressions for the sensor locations and have large uniform degrees of freedom ...
Scientists have transformed a groundbreaking 2D nanomaterial called MXene into an even more powerful 1D form—tiny scroll-like tubes that are incredibly thin yet highly conductive. By rolling flat ...
Abstract: In this paper, the problem of joint time-of-arrival and two-dimensional direction-of-arrival (TOA/2D-DOA) estimation is solved using space-frequency nested array (SFNA) motion. SFNA is ...
