太赫兹波在介质中传播的FDTD分析
FDTD analysis of terahertz pulse traveling in media
摘要
Abstract
Finite difference time domain method is one of the most active numerical methods applied in the electromagnetic field, which can effectively deal with the scattering of electromagnetic pulses by particles in complex media, as well as the propagation of ultra-wideband electromagnetic pulse in dispersive media. Almost all media, regardless of whPther there is ahsorption spectrum in terahertz(THz) band. may influence the terahertz wave transmission in it. RPqearch of terahertz wave propagation in the media is important for the optimization of terahertz systems. as well as the analysis and design of applied terahertz technologies. This study simulated the terahertz wave transmission in thP scattering media,indicating the possihility of adopting terahertz wave in the interferometer for hallistic velocity measurement; and simulated terahertz pulse propagation in dispersive media, providing the basis for crystal selection in terahertz time domain spectroscopy system.关键词
