Finding phase delay between two ports

How to get the phase delay, when input is given to one port and received in another port? In openEMS magnitude of the S21 can be found. But how to get the phase difference?

Re: usage of different prio is giving entirely different return loss curve!

I am facing this issue for the first time.. I have given prio for antenna & groundplane 10, and was checking for the interference caused by metals near the antenna.. It is just a floating metal, used AddMetal function and imported STL file for the structure.. Is it may be due to STL?? They are not t...

usage of different prio is giving entirely different return loss curve!

I am giving prio of one metal as 10 and for antenna also 10. Is it matters that the metal which is not at all intersecting the substrate or any other plane. Changing the prio to 5 for metal is giving entirely different curve! Can anybody explain it?? Metal is just a plain floating below antenna and ...

Feed excitation

How exactly a feed works? what and all components does it has? like is it a metal plate or it is just voltage changes from one point to another point? Can anybody tell me the model used for feed and any documentation for the feed..

Re: Convergence value

Is -30dB convergence is good enough to get proper results or not? It is not about simulation time..

Convergence value

Hey, I am designing an antenna and I have given timesteps 100000 and Endcriteria as -5(-50dB). But even after 100000 timesteps convergence value is -36 to -38dB(convergence value is saturating nearly at -35dB after 40000 time steps). Is the final results will be fine or do I have to increase time st...
