Anyone can review my simulation structure [CST]

Dear All friend,
Anybody can help me review and consider my structure of CST MWS simulation.Is it correct ?
The propose of my structure is placed the sample dielectric constant ε=5.1 in the rectangular wave guide with dominant mode TE10.For the result of port setting i have check the value that cal by CST and by manual cal ,it is correct.But My problem is how to know that the result of E-field distribution through the sample is corrrect or not.Somebody know about how to prove the structure that make in CST 's result are correct per theory.
Please help to run my stucture and help advise please , I use CST MWS 5.
Thanks and Regards,
