研究目的
To point out the incorrect calculation of the absorption rate in the proposed broadband terahertz metamaterial absorber by Pan et al. due to the negligence of the cross-polarization reflection component.
研究成果
The proposed broadband terahertz metamaterial absorber by Pan et al. has poor performance due to the incorrect calculation of the absorption rate, which neglected the cross-polarization reflection component. The actual absorption peaks are significantly lower than reported.
研究不足
The study is limited to the re-simulation of the proposed BTMA structure and does not propose a new design or improvement to the absorber's performance.
1：Experimental Design and Method Selection:
The study involves re-simulating the proposed broadband terahertz metamaterial absorber (BTMA) to verify the absorption rate calculation, considering both co-polarization and cross-polarization reflection components.
2：Sample Selection and Data Sources:
The study uses the same structural parameters as Pan et al.'s proposed BTMA for simulation.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The simulation involves calculating the absorption rate by considering both co-polarization and cross-polarization reflection components.
5：Data Analysis Methods:
The analysis compares the reported absorption rates with the actual absorption rates obtained by considering all reflection components.
