摘要

本文研究了表面等离子激元(SPP)模式与偶极子模式在太赫兹下的相互作用。完美超材料吸收体(PMA)由超表层、介电间隔层和金属基底组成。研究了PMA产生的SPP模式与晶胞晶格常数的关系。此外，观察到高质量因子共振，这已经成为许多研究的主题，因为高质量因子对于实际应用是非常理想的。

Analysis of the coupling between surface plasmon polariton mode and dipole mode at terahertz metasurface absorber

We have investigated the interaction of surface plasmon polariton (SPP) mode with dipole mode at terahertz perfect metamaterial absorber (PMA) consisted of a metasurface layer, a dielectric spacer layer, and a metallic ground. The dependence of SPP modes generated by PMA on the lattice constant of the unit cell was investigated. Also, high-quality-factor resonance is observed, which has been a subject of numerous investigations since an elevated quality factor is highly desirable for the practical application.
