Working code for extraction of meta material parameters

I have the proper code for extraction of meta-material parameters like permittivity , permeability, phase and impdeance


steps to follow:
1) save ur s11 data as s11.txt
2) similarly save s22 -- s22.txt // argument of s11 as arg_s11 /// argument of s22 as arg_s22
3) use the code and specifiy the locations of these text files

and run............it will work 100%

if any1 requires the code,let me know here or by mail.......
