Flexible phased arrays potentially enable diverse applications not permitted by rigid systems; however, they introduce ambiguity in antenna element positions. If this position can be overcome, flexible perform the full suite of array functions: beam steering, wavefront engineering, and focusing. Furthermore, shape reconstructions used for beyond beamforming. We propose a framework to reconstruc...

In this paper a comprehensive calibration procedure for MIMO system is proposed. This technique is able to eliminate effects of the following three unwanted components from MIMO measurement data, i.e. multiple transmitters characteristic, multiple receivers characteristic, and mutual coupling in array antenna elements. The numerical simulation proves that there is an improvement in the DOA esti...

Weakly interacting lattices of coupled maps can be modeled as ordinary coupled map lattices separated from each other by boundary regions with small coupling parameters. We demonstrate that such weakly interacting lattices can nevertheless have unexpected and striking effects on each other. Under specific conditions, particular stability properties of the lattices are significantly influenced b...
