AMIMO Microwave Wireless Power Transfer
2019 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2019In addition to its uses in wireless Communication and Radar systems, Microwaves have been proposed for Radiative Wireless Power Transfer (RWPT). Many systems were designed for microwave wireless power transfer (MWPT) between earth and space, in space and on earth.

Wireless power beam device using microwave power transfer
2014 IEEE Wireless Power Transfer Conference, 2014The authors proposed a novel WPT system using ceramic dielectric resonators. Unloaded Q of ceramic resonator is several tens of thousands depending on the material. Thus, we can expect much longer transmission distance by using ceramic resonator. It was confirmed that the power transfer of this system was conducted by a combination both of coupling in ...

Wireless Power Transfer Using Microwaves
2017In this paper, a model has been presented which transfers electric power without wires by using microwaves. A breadboard model of receiving antenna called rectenna is developed for preliminary experiments including wireless power transmission. The paper presents one to one MPT system in which electric power is transferred at radio frequencies ranging ...

Microwave Power Sensors With Integrated Filtering Function for Transfer Power Standards
IEEE Microwave and Wireless Components Letters, 2020This letter presents a bolometric power sensor for transfer power standards in a waveguide. This is a novel design of the microwave power sensor with an integrated filter function. An analytical power sensor synthesis technique using the coupling matrix is presented here for the first time.

Resistive power splitter in microwave power standard calibration transfer
Measurement, 1988The problem of accurately calibrating one power meter from another is not trivial, certainly when precise broad-band measurements are required. The main error sources — mismatches — often impair accuracy very seriously and correction methods for these errors are either time-consuming or complicated.

Enhancement of received power in far-field microwave wireless power transfer
2020 IEEE Wireless Power Transfer Conference (WPTC), 2020A parabolic dish reflector (PDR) is designed and fabricated to convert the plane wave to spherical wave at the focus. The performance of PDR made from aluminum and Polydimethylsiloxane (PDMS) coated with aluminum is carried out. It is observed that the performance of the PDR made from PDMS is same as that made from aluminum, thus the proposed PDR made ...

Termination Transformation Theorem for Microwave Power Transfer Networks
Journal of Circuits, Systems and Computers, 2019Termination 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

Microwave Power Beaming for Long Range Energy Transfer
8th European Microwave Conference, 1978, 1978Current studies by NASA have identified space solar power as a potential long term viable candidate for efficient energy transfer at orbital ranges using a microwave beam. This paper will describe some of the power-aperture relationships leading to a potential feasible design of a power beaming system.
