Dear siesta users I am trying to calculate the optical properties of graphene. I have the .EPSIMG file and i want to calculate different optical properties out of it. I used the command input < System label.EPSIMG but siesta gave the following message :
"Yagi-Uda antenna analysis programs, version 1.19 Written by Dr. David Kirkby Ph.D. (G8WRB, email:[email protected]) This program asks for length, diameter and position of antenna elements then writes them to a file you specify. Data is written in m (metres) Numerical Recipes run-time error... The minimum frequency has been set higher than the centre frequency ...now exiting to system... Enter any notes on this design (up to 400 characters): Enter a filename to write data to Enter the centre frequency in MHz Enter the minimum frequency in MHz Enter the maximum frequency in MHz Enter the frequency steps in MHz" I can t understand the message and i think it is irrelevant . I will be thankful if someone helps me with regards S.Gholami
