Supplementary Data for Publication "Powering Mobile Sensor Nodes in Fluidized Beds: A Non-Invasive RF Energy Harvesting Proof-of-Concep"

This dataset provides the supplementary measurement and 3D simulation data for the manuscript "Powering Mobile Sensor Nodes in Fluidized Beds: A Non-Invasive RF Energy Harvesting Proof-of-Concept". The research demonstrates a retrofittable wireless power transfer system that repurposes a metallic fluidized bed vessel into a 5.23 GHz multi-mode microwave cavity resonator to power battery-free sensor nodes. The provided files include CST Studio Suite electromagnetic simulation models (.cst) that evaluate different standard flanges as microwave feed ports and emulate field attenuation during active liquid injection. Additionally, it contains raw experimental data (.csv) characterizing the power conversion efficiency (PCE) of a custom-designed, compact RF-to-DC rectifier prototype across varying input powers and load resistances. This work is part of the DFG-funded CRC1615 (Project A07).
