Trying to get field overlay data correctly

  Hi,
  
  When I send the TE mode wave(in -x direction) using floquet port from bottom of the box and show in overlay, it shows like this ( it is just a empty air box with and pec to block the signal propagation):
  
  Now I want to get the value of those E field. Therefore, I set the far field(with phi = 0, theta from -180 to 180).
  
  When I got the plot, I got like this.
  
  The graph show the E field at 15000GHz, 20000GHz and 25000GHz using infinite sphere(phi = 0 all the time)
  
  Could someone explain why I got this E-field graph? In my understanding, infinite sphere at theta = 0 is at top of the z aixs. And field overlay shows all the waves are blocked by the pec at the top of the z axis. However, I can not understand why I still got value at the graph. Especially at theta at 0, which clearly indicates the top part of z axis, I got E field value at 687mV at 25000GHz.
  
  Thanks!
