How to determine the near field of a structure in CST

Hi,
can you give me the steps to determine the near field of a structure in CST
thank you for your help

Do you mean you want know the steps to acquire field data within the 2d^2/lambda distance (nearfield) of your structure?

Hi Element7k, is it possible for CST to get the field data within 2d^2/lambda of a structure? I'm interested about this.
