EBG Simulation using EMPIRE software

hi,
I've tried to simulate an ebg structure using empire software. I used a plane wave excitation and near field to far field transformation as described by literature 'FDTD Modelling of finite size ebg structure' in empire website. But I receives an error 'ValueError: bad marshal data'. Somebody please help me suggesting what is wrong with my simulation. And I also need to know what is the purpose of plane wave excitation and near field to farfield transformation.

Thanks,
yvonne82:D

hi yvonne.....

i am also working on same thing ...and i also want to obtain dispersion diagram....oor phase reflection versus frequency graph using empire......if you know plz send me procedure using empire.....hope we you will know the procedure...i have made the design ..bt i dont know how to obtain that "phase reflection versus frequency graph" or dispersion diagram.

Do you reach to a solution of your problems Navdeep and yvonne82?

i have tried to simulate this ebg structure using empire and it displays error that nftff box should be considered at distance from structure/boundary.

i dont know at what distance it should be placed from boundary ...

i am trying ...again it is creating error.
