fdtd模拟二维表面等离子体波导结构的电磁场分布

详 情 说 明

The simulation of finite-difference time-domain (FDTD) can be used to analyze the electromagnetic field distribution of two-dimensional surface plasmon waveguide structures. This analysis can be particularly useful in the field of photonics, where there is a growing interest in plasmonics due to its potential for subwavelength confinement of light and enhancement of light-matter interactions. The FDTD method involves discretizing Maxwell's equations in both space and time, and then solving for the electric and magnetic field components at each point in space and at each time step. By simulating the behavior of surface plasmons in various waveguide structures, researchers can gain a deeper understanding of plasmonic effects and optimize the design of plasmonic devices for various applications.
