講座內容：

A phased array is composed of an array of antenna elements that are excited individually. Via tuning the phase profile and amplitude profile of the excitations, a phased array is capable of generating a narrow electromagnetic beam and steering the beam without any mechanical adjustments. Phased arrays have widespread applications in wireless communication and radar. The phased array technique may also be employed to transmit power (in contrast to information/signal) wirelessly over long distances (on the order of meters, ten meters, or longer). Nevertheless, employing phased arrays for wireless power transmission encounters various technical challenges that are typically not present in wireless communication or radar applications. As one of the primary challenges, the well-established far-zone condition is usually not satisfied when a phased array is employed as a wireless power transmitter. This presentation intends to comprehensively address the technical complications associated with the near-zone condition when the phased array technique is applied for wireless power transmission. Specifically, a closed-form formulation is derived to estimate the electromagnetic radiation as well as the power transmission efficiency when a phased array is employed to transmit wireless power under the condition of near-zone (rather than far-zone).
