An Inclusive Survey on Array Antenna Design for Millimeter-Wave Communications

open access: yesIEEE Access, 2019
The enormous growth of wireless data traffic in recent years has made the millimeter-wave (mm-wave) technology as a good fit for high-speed communication systems. Extensive works are continuing from the device to system, to the radio architecture, to the

Volume Bragg grating external cavities for the passive phase locking of high-brightness diode laser arrays : theoretical and experimental study [PDF]

open access: yes, 2011
We describe the theoretical modeling of the external-cavity operation of a phase-locked array of diode lasers in two configurations, the self-imaging cavity based on the Talbot effect and the angular-filtering cavity. Complex filtering functions, such as

Direction of Arrival Estimation of Generalized Nested Array via Difference–Sum Co-Array

open access: yesSensors, 2023
To address the weakness that the difference co-array (DCA) only enhances the degrees of freedom (DOFs) to a limited extent, a new configuration called the generalized nested array via difference–sum co-array (GNA-DSCA) is proposed for direction of ...

Minimal Energy Configurations of Finite Molecular Arrays [PDF]

open access: yesSymmetry, 2019
In this paper, we consider the problem of characterizing the minimum energy configurations of a finite system of particles interacting between them due to attractive or repulsive forces given by a certain intermolecular potential. We limit ourselves to the cases of three particles arranged in a triangular array and that of four particles in a ...

L-Shaped Sparse Array Structure for 2-D DOA Estimation

open access: yesIEEE Access, 2020
In order to improve the performance of two-dimensional (2-D) direction-of-arrival (DOA) estimation, an L-shaped sparse array structured by two new sparse linear arrays is proposed. Each part of the proposed L-shaped array is used for one-dimensional (1-D)
