Fourier Plane-Wave Series Expansion for Holographic MIMO Communications [PDF]
IEEE Transactions on Wireless Communications, 2021 Imagine a MIMO communication system that fully exploits the propagation characteristics offered by an electromagnetic channel and ultimately approaches the limits imposed by wireless communications. This is the concept of Holographic MIMO communications.

Compact holographic sound fields enable rapid one-step assembly of matter in 3D
Science Advances, 2023 Acoustic waves exert forces when they interact with matter. Shaping ultrasound fields precisely in 3D thus allows control over the force landscape and should permit particulates to fall into place to potentially form whole 3D objects in “one shot.” This ...

Holographic Integrated Sensing and Communication
IEEE Journal on Selected Areas in Communications, 2022 To overcome spectrum congestion, a promising approach is to integrate sensing and communication (ISAC) functions in one hardware platform. Recently, metamaterial antennas, whose tunable radiation elements are arranged more densely than those of ...
