Directional Radiation Technique for Maximum Receiving Power in Microwave Power Transmission System
IEEE Transactions on Industrial Electronics, 2020Directional radiation (DR), a distinguishing feature of a microwave power transmission (MPT) system, suitably shapes and properly steers an intensified beam toward a specific target area. Coupling more radiated energy to the receiving aperture, DR technique benefits system efficiency and brings great flexibility, which entails further investigation ...

Maximum Achievable Rates with Transmission and Circuit Total Power Constraints
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017In classical information and communication theory, channel capacity and achievable rate over Gaussian channels, whether for constant or fading channels and whether for single user or multiple users, are characterized as functions of the power that is used for the transmission of the information.

Energy Efficiency Evaluation of Uplink Transmissions with Maximum Power Constraint
2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017Energy efficiency of uplink users is critical for evaluating the energy consumption of heterogeneous cellular networks (HCNs) with heavy loading. The energy efficiency of user equipments (UEs) in HCNs depends heavily on power control scheme as well as maximum power constraint.

Optimizing Viscosity for Maximum Power in a Hydrostatic Transmission Wind Turbine
BATH/ASME 2022 Symposium on Fluid Power and Motion Control, 2022Abstract In basic hydraulic theory, efficiency is dependent on volumetric and mechanical losses. Components dominated by mechanical losses favor low viscosity fluids, while those dominated by volumetric losses favor high viscosity fluids. For a hydrostatic transmission (HST), efficiency of both the pump and motor must be considered.

Maximum Aperture Power Transmission in Lossy Homogeneous Matters
IEEE Antennas and Wireless Propagation Letters, 2015We apply array signal processing techniques to the transmitting aperture field modes in order to determine the optimal field distribution that maximizes the power transmission through lossy media between a transmitting and an ideally receiving antenna aperture.

Constant maximum power control for dynamic wireless power transmission system
2017 IEEE PELS Workshop on Emerging Technologies: Wireless Power Transfer (WoW), 2017Dynamic Wireless Power Transmission (DWPT) uninterruptedly charges the moving Electric Vehicles (EVs) through the powered roadway, providing a potential solution to the battery bottleneck. EVs need to obtain energy as much as possible to guarantee proper functioning.

Maximum Active Power Transmission Efficiency and Apparent Power Definition with Arbitrary Waveforms
European Journal of Electrical Engineering, 2022A proof of the theorem giving the maximum available active power with constant transmission losses (i.e., maximum efficiency) valid for arbitrary waveforms, is proposed. This makes it possible to rigorously generalize the definitions of power factor based on the definition of apparent power as the maximum power available to apply them to systems with ...

Maximum Power Transmission in Mass-Limited Radio Systems
IEEE Transactions on Communications, 1982A simple fundamental relationship is derived between antenna gain and transmitter power which maximizes the effective radiated power in mass-limited satellite systems. In the most common case, maximum effective radiated power is achieved when the payload mass is divided equally between the antenna system and the power system.
