Radio frequency (RF) energy transfer and harvesting techniques have recently become
alternative methods to power the next-generation wireless networks. As this emerging …

Continuous advances in ultralow-power electronics are a fundamental driving force of
developing far-field wireless power harvesting techniques, which generally harnesses …

The idea of wireless power transfer (WPT) has been around since the inception of electricity.
In the late 19th century, Nikola Tesla described the freedom to transfer energy between two …

Power beaming is the efficient point-to-point transfer of electrical energy across free space
by a directive electromagnetic beam. This paper clarifies the basic principles of power …

This paper presents an overview of passive Radio Frequency (RF) energy reception and
power harvesting circuits for isolated communications and computing systems lacking …

We present the first power over Wi-Fi system that delivers power to low-power sensors and
devices and works with existing Wi-Fi chipsets. Specifically, we show that a ubiquitous part …

This paper discusses far-field wireless powering for low-power wireless sensors, with
applications to sensing in environments where it is difficult or impossible to change batteries …

Since the very beginning of RF and microwave integrated techniques and energy
harvesting, Schottky diodes are most often used in mixing and rectifying circuits. However, in …

An implantable rectenna, which consists of a planar inverted-F antenna (PIFA) and a rectifier
circuit, is proposed for far-field wireless power transfer. The PIFA has a folded ground plane …

This paper addresses design and implementation of integrated rectifier-antennas
(rectennas) for wireless powering at low incident power densities, from 25 to 200 μW/cm^2 …
