Optimization of Super-Directive Linear Arrays with Differential Evolution for High Realized Gain
In this paper, we assert that it is crucial to consider the trade-off between directivity and overall efficiency (to achieve high realized gain) before employing super-directive arrays in real-world applications.
Super-Directive Antenna Arrays: How Many Elements Do We Need?
Thus, it is observed that super-directivity can be obtained in an array with a maximum of five elements.
Graph Attention Network Based Single-Pixel Compressive Direction of Arrival Estimation
In this paper, we present a single-pixel compressive direction of arrival (DoA) estimation technique leveraging a graph attention network (GAT)-based deep-learning framework.
Intelligent Reflecting Surfaces with Spatial Modulation: An Electromagnetic Perspective
Using a secondary source present in a wireless communication environment, such as a backscatter tag, it is possible to leverage the incoming radiation from the source as a reference-wave to synthesize the desired wavefront across the reflecting surface, radiating a field of interest.
The Road to 6G: Ten Physical Layer Challenges for Communications Engineers
While the deployment of 5G cellular systems will continue well in to the next decade, much interest is already being generated towards technologies that will underlie its successor, 6G.
