In wireless power transfer, a concept originally conceived by Nikola Tesla in the 1890s, energy is transmitted from a power source to a destination over the wireless medium. The use of wireless power transfer can avoid the costly process of planning and installing power cables in buildings and infrastructure. One of the challenges for implementing wireless power transfer is its low energy trans...

In conventional communication systems, the use of radio frequency (RF) signals is mainly constrained on information transfer. However, RF signals also contain energy and this fact leads to the emergence of various new research areas, like RF-enabled wireless power transfer (WPT) where wireless receivers could harvest energy from RF signals radiated by an energy transmitter. There is another tec...

Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

Abstract In the last two decades, metamaterials and metasurfaces have introduced many new electromagnetic (EM) theory concepts inspired contemporary design methodologies for EM devices systems. This review focuses on recent advances in (MMs) simultaneous wireless information power transmission (SWIPT) technology. increasingly complex world, digital coding programmable enabled commercial opportu...

The joint design of spatial channel assignment and power allocation in Multiple Input Multiple Output (MIMO) systems capable of Simultaneous Wireless Information and Power Transfer (SWIPT) is studied. Assuming availability of channel state information at both communications ends, we maximize the harvested energy at the multi-antenna receiver, while satisfying a minimum information rate requirem...
