Noise Suppression and Precise Phase Control of a Commercial S-Band Magnetron

open access: yesIEEE Access, 2020
We demonstrate noise suppression and precise phase control of a commercial 2.45GHz magnetron aiming for wireless power transfer application. The impurity of the microwave spectrum was confirmed to be due to the switching frequency of 76kHz in the power ...

Kinetics and Quality of Microwave-Assisted Drying of Mango (Mangifera indica)

open access: yesInternational Journal of Food Science, 2016
The effect of microwave-assisted convective air-drying on the drying kinetics and quality of mango was evaluated. Both microwave power and pretreatment time were significant factors but the effect of power was more profound.

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 ...

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
