Abstract: (3639 Views)
In this paper we analyze the effect of changing the geometrical parameters of a transmission grating in changing the phase of the outgoing waves. The numerical study is based on the Finite Element Method (FEM) in frequencies from 95THz to 215 THz. Lastly we show that with a proper selection of the width and changing the thickness of wires we can reach up to 110 degree phase difference between the incoming and transmitted waves.
