Termination Transformation Theorem for Microwave Power Transfer Networks

open access: yesJournal of Circuits, Systems and Computers, 2019
Termination transformation theorem (TTT) proposed in this work transforms a doubly complex terminated microwave power transfer network (PTN) to an equivalent doubly resistively terminated termination transformed network (TTN) which is essentially a filter network. In this work, the transducer power gain (TPG) formula, Tgen, based on S and transmission

Ranging On-Demand Microwave Power Transfer in Real-Time

open access: yesIEEE Microwave and Wireless Components Letters, 2021
This letter presents a novel system for real-time ranging wireless power transfer (WPT) “on-demand.” This is obtained by duty-cycling a frequency diverse array (FDA) and by suitably choosing the time delay of the pulse. First, the theoretical design of the time- and frequency-dependent array is developed, and then it is applied to predict the ranging ...
