  Hello, everyone. I have a problem. I I changed the wavelength of the plane wave to a different frequency, but I didn't get the result.

  It might be because the wavelength in monitor is far away from the source spectrum. Please check
  
  It is suggested to use the default monitor settings when you change source spectrum.

    My test frequency is between KHZ and GHz, can it be realized? Thanks

  Yes, it whould work. But it will needs long simulation time if the mesh is too fine. Now the wavelength is in cm or meters so mesh/simulation time much be proper. Usually the default settings should be modified.
