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 .
