摘要

针对自旋电子太赫兹发射器的结构，研究了局部表面等离子体共振导致铁磁薄膜中电磁场放大的规律。通过数值模拟确定了 Pt/Co 和 Pt/Co/W 等离子体结构的最佳参数，这些参数可使薄膜在 800 纳米波长处产生最大光吸收。结果表明，使用质子结构可以将 Pt/Co 和 Pt/Co/W 结构的光吸收分别提高到 25% 和 18%。这些结构具有很高的极化灵敏度，表现为很高的吸收各向异性，相当于 0.9。

Resonant Plasmonic Structures for Spintronic THz Emitters

The laws of amplification of electromagnetic fields in thin ferromagnetic films due to the local surface plasmon resonance have been investigated for structures of spintronic THz emitters. The optimal parameters of Pt/Co and Pt/Co/W plasmonic structures, providing maximum optical absorption in the films at a wavelength of 800 nm, have been determined using numerical simulation. The results show that the use of plasmonic structures makes it possible to increase the optical absorption in Pt/Co and Pt/Co/W structures to 25 and 18%, respectively. The structures are found to have high polarization sensitivity, which manifests itself in high absorption anisotropy, equal to 0.9.
