Hi
i am a new student to this field
i am trying to do a simulation to analyze the Electric field generated by a nano scale gap in a thin gold layer .
i am using OPTFDTD as the simulation software .
I cannot figure out how to setup the excitation parameters for the simulation .
(specially the excitation angle for the simulation,and how to separate the plasmon field for analyzing )
it would be really grateful if someone could give me some advice or help on this .
thank you in advance .
