Circuit-Theoretic Modeling and Simulation Study of Near-Field MIMO Arrays of Dipole Antennas

open access: yesActive and Passive Electronic Components
Near-field mutual coupling among closely spaced antennas limits the deployment of wireless MIMO interconnects in chip-to-chip communication. This paper presents a circuit-theoretic modeling and simulation study of near-field MIMO (NFMIMO) systems using 1

Obstacle-Immune Microwave Wireless Power Transfer System Based on Amplitude-Dependent Caustic Metasurface. [PDF]

open access: yesAdv Sci (Weinh)
This paper innovatively proposes an advanced microwave wireless power transfer (MWPT) system based on the amplitude‐dependent caustic metasurface generating the circular Airy beam. The proposed MWPT system will advance the research and development of circular Airy beams in the radio frequency domain.
