Hi, recently,I am trying to use FDTD to simulated surface plasmon, after seting total field/scattered field for TE (Ex,Ey,Hz)model,I don't know how to introduce a finite width plane wave in the total field region. After the ordinary procedure to generate a plane wave at the vitural interface, the plane wave will full fill the total field region. Can anybody give me a idea of how to generate a finite width plane wave in the total region? thanks very much!
