In this paper, we investigate the issue of 2-D direction-of-arrival (DOA) estimation of multiple signals in co-prime planar arrays, where phase ambiguity problem arises due to the large distance ...

We report the synthesis and characterization of covalent dyads and multiads of electron acceptors (A) and donors (D), with the purpose of exploiting their nanophase separation behavior toward (a) ...

The method of two-dimensional not equidistant antenna arrays design is based on magic squares is proposed. The properties of antenna arrays (directivity pattern, side lobe level, frequency overlap) ...
