摘要

采用基于梯形递推卷积技术的时域有限差分方法，对三维存根型等离子体滤波器进行了分析。计算出三维滤波器的峰值透过率为50%，而二维滤波器的峰值透过率大于90%。为了提高三维滤波器的透射率，我们在短段插入了介电材料。结果表明，在短段填充SiC后，其透过率可提高到80%以上。

Numerical investigation of a three-dimensional stub-type plasmonic filter

A three-dimensional (3D) stub-type plasmonic filter is analyzed using the FDTD method based on the trapezoidal recursive convolution technique. The peak transmissivity of the 3D filter is calculated to be ≃50%, while the two-dimensional filter yields more than 90% transmissivity. To improve the transmissivity of the 3D filter, we insert a dielectric material into the stub section. It is found that the transmissivity is increased to more than 80% with the stub section being filled with SiC.
