OK! I used SiO2 sphere which diameter was 400nm. And wavelength was 355nm.

"behind the TFSF source" 



 "in front of the plane wave source"


After filtering low NA region

After filtering "cross mark", scattering signal is observed slightly. 

I wanna know what causes "cross mark".

Best regards
