DOI: 10.1109/lcomm.2019.2952595

Abstract: Most of compressive sensing Direction of Arrival (DoA) estimation schemes in the literature employ a uniform array for the simplicity and mathematical tractability. Non-uniform array geometries can enhance the resolution performance, substantially. However, they suffer… read more here.

DOI: 10.1109/tsp.2024.3386018

Abstract: Gridless direction-of-arrival (DOA) estimation with multiple frequencies can be applied in acoustics source localization problems. We formulate this as an atomic norm minimization (ANM) problem and derive an equivalent regularization-free semi-definite program (SDP) thereby avoiding… read more here.

DOI: 10.1186/s11671-019-3184-7

Abstract: The fabrication of a uniform array film through assembly of colloidal building blocks is of practical interest for the integrated individual and collective functions. Here, a magnetic assembly route was put forward to organize monodisperse… read more here.

DOI: 10.3390/mi13122233

Abstract: This research presents the design of time-modulated antenna arrays with UWB performance. The antenna arrays consider a linear topology with eight UWB disk-notch patch antennas. The technological problem is to find out the optimum antenna… read more here.
