query regarding HFSS

hi

i need some guidance about HFSS (high frequency structure simulator)

1)can anyone please tell me how to generate spherical waves in HFSS.....i generated them using EXCITATIONS/INCIDENT WAVE/SPHERICAL in a box but they are not behaving like spherical waves....and also tell me what type of boundaries of the box i should define

2)same question for plane waves

waiting for the quick and kind response

Hi,
Could you share what you have found out for the incident wave ?

I used normal PML for the big boundary box, but my plane-wave seems to NOT emitting any power !
