面向低空经济ISCPT场景的多维信息超表面框架、关键技术与展望OA

The development of the low-altitude economy imposes integrated requirements on unmanned aerial vehicles for highly reliable communication,real-time environmental sensing,and continuous energy replenishment.Integrated sensing,communication,and power transfer(ISCPT)provides a systematic technical pathway for jointly addressing these requirements.Featuring low profiles,low cost,and programmable wavefront manipulation,information metasurfaces can serve as reconfigurable electromagnetic apertures in low-altitude sensing and communication networks.Building on recent advances in information metasurfaces for sensing,power transfer,communication,and their integration,this paper proposes a multidimensional information metasurface analysis and design framework for ISCPT scenarios in the low-altitude economy.Starting from low-altitude scenario constraints and the functional requirements of power transfer,communication,and sensing,the framework first identifies the performance objectives of different tasks,then determines the electromagnetic quantities required to achieve these objectives,and finally maps them to specific hardware architectures and network implementations.First,the individual capabilities and performance metrics of the power-transfer,communication,and sensing dimensions are summarized.Three two-function integration modes are then discussed,namely integrated sensing and communication,simultaneous wireless information and power transfer,and integrated power transfer and sensing.Furthermore,the control capabilities required for multi-objective coordination are analyzed in terms of physical degrees of freedom,including amplitude,phase,frequency,polarization,temporal response,spatial modes,nonlinear response,and radiation/scattering states.Given the current scarcity of fully integrated prototypes jointly supporting power transfer,communication,and sensing,three-way functional coordination is identified as a research roadmap toward low-altitude ISCPT.Key issues including low-altitude dynamic constraints,multidimensional decoupled control,closed-loop resource allocation,and distributed networking are also discussed.
