hi
when I simulate my antenna (for example in CST), can I talk about surface wave excitation based on antenna's radiation pattern? how to know that surface wave excited based on simulation results?!!! can any one explain please?
thanks for your time.
Hello,
You can verify that, by checking the surface power loss density at your operating frequency, or by the electric field animation along the cross section of your structure, if there is any waves propagate along your metalic sheet then it means that you have a surface wave propagation.
thank you Mr Said Choukri for explaining
and thanks Mr Maxim Vengerov
Dear Maryam,
Simpler than all that I would set a field-monitor to the operating frequency of your patch. If you want an E-field and H-field monitor. With that in 2D/3D results in the corresponding folder you will be able to see the electric field, magnetic field and currents in your patch which will surely give you valuable information of its performance.
Best regards,
Miguel
