The importance of medical data and the crucial nature of the decisions that are based on
such data, as well as the large increase in its volume, has encouraged researchers to …

In this paper, low sidelobe radiation pattern (ie, pencil-beam pattern) synthesis problem is
formulated for symmetric linear antenna arrays. Different array parameters (feed current …

Antenna arrays are integral to high-performance systems such as radar, wireless
communications, satellite communications, radio astronomy, and medical imaging …

Phase Perturbation Method (PPM) is introduced as a new phase-only synthesis method to
design reflectarray antennas so as their sidelobe level is reduced. In this method, only the …

A multilevel subarray RF modularization technique is presented to construct a hierarchical
beamforming network (BFN) for phased array of antennas. In contrast to the conventional …

Abstract The Grey Wolf Optimizer (GWO) is a very recently developed and emerging swarm-
intelligent algorithm. The GWO algorithm was inspired by the social dominance hierarchy …
