研究目的
To design a dual polarized metasurface collector for electromagnetic energy harvesting that channels absorbed power to a resistive load rather than dissipating it in the dielectric substrate.
研究成果
The proposed dual polarized metasurface collector achieves high efficiency in electromagnetic energy harvesting by channeling absorbed power to a resistive load. The design's extension to a super cell allows for energy collection from two different polarizations, making it suitable for various applications including wireless power transfer and RFID tags.
研究不足
The design's efficiency is dependent on the optimal resistive load and the positioning of the via, which may limit its application in scenarios where these parameters cannot be precisely controlled.
1：Experimental Design and Method Selection:
The design involves a wheel-shaped resonator for power absorption and a via to channel the absorbed power to a resistive load. A super cell of four wheel-shaped resonators was designed for dual polarization energy collection.
2：Sample Selection and Data Sources:
The unit cell dimensions and materials were specified, including a Rogers TMM10i substrate with specific properties.
3：List of Experimental Equipment and Materials:
ANSYS HFSS for simulation, Rogers TMM10i substrate, copper for resonator, and a resistive load.
4：Experimental Procedures and Operational Workflow:
The resonator was simulated in a waveguide with periodic boundary conditions to mimic a large array with TEM wave excitation. Material parameters were tuned for full absorption and maximum power delivery to the load.
5：Data Analysis Methods:
Absorption and power dissipation across the load were calculated from simulation results.
