phase of the radiated electric field from dielectric sphere in CST

$
0
0

  frequescy 5..10 GHz

for the mie scattering resonance frequency i use 7.5GHz

dipole length L=40mm

epsilon=16 thus from the formula lambda=sqrt(epsilon)*d

so the radius is 4.71mm

i put a probe tanjectual to the surface of the sphere and tried to get the phase of the radiated field,but i get thats its zero  allthough i changed the radius and he osition of the probe.

i see no change in phase,why i have zero phase ??

i tried to change the parameters and still i get phase zero which is wrong

thanks




i changed the size and position of the dipole and still get zero phase,which contradicts the theory .
