After the simulation I evaluated the field Ez in the middle of the port which I supposed the magnitude was going to be 1V\/0.9mm=1111V\/m but is actually 2222V\/m (2*supposed electric field). I did the same simulation with solution type modal with the integration line from bottom to top (0.02W to have 1V with the port 50Ohm), this time the magnitude of Ez was 3142V\/m (2*sqrt(2)*supposed electric field).<\/p>\n<p>Do you have ideas why I got those results?
