Integrated circular optical phased array [PDF]
EPJ Web of Conferences, 2021 Existing OPAs are typically based on 2D rectangular arrays or 1D linear arrays. Both approaches present a limited field-of-view (FOV) due to the presence of the grating lobes when the element spacing is larger than λ/2.

Robust approaches to remote calibration of a transmitting array [PDF]
, 2010 We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna.

Adaptive beamforming for large arrays in satellite communications systems with dispersed coverage [PDF]
, 2011 Conventional multibeam satellite communications systems ensure coverage of wide areas through multiple fixed beams where all users inside a beam share the same bandwidth. We consider a new and more flexible system where each user is assigned his own beam,
