Wavenumber-Division Multiplexing in Line-of-Sight Holographic MIMO Communications [PDF]
Starting from first principles of wave propagation, we consider a multiple-input multiple-output (MIMO) representation of a communication system between two spatially-continuous volumes. This is the concept of holographic MIMO communications.
