CST Power Monitor Problem

Hi to all

i've simulated an article with CST and got the same Result , but when i want to Define Power monitor to calculate surface integralof (  E × H ) over the surface of the port , unfortunately i can't define , so could you please Help me? ( and also i've defined impedance line on ports for calculating the characteristic impedance).

According to the article :
most appropriate definition of characteristic impedance is based upon power and voltage . Z = V·V /P .
An impedance line is defined on the ports to integrate electric field and thereby to calculate voltage, while power P has been calculated from the surface integral of (  E × H ) over the surface of the port.

and for example how can i obtain the variation of normalized propagation constant with the
wavelength as a function of insulator width w.


last question , i want to draw below Filter with Extrude Tool , but i couldn't , how can i do it?
