Dear researchers, As you know from the linear degree of polarization at 90-degree, one can find out the resonance modes:
PL(90)=I90-I0/I90+I0=|a1|^2-|b1|^2/|a1|^2+|b1|^2
where a1 and b1 are the electric and magnetic dipole according to Mie's theory. In the same sense, can we relate the circular degree of polarization to the scattering modes? Similarly, can we also relate the phase shift (delta) and polarization angle (phi) between the orthogonal components of E-field to the scattering resonance modes?
Thanks
with regards
Hi...
- When you have extremely large E, you can relate them with each other. I think it was dipole moment= polarization* E-field....As you know dipole moment has a relation with phase shift and I think you can relate the circular degree of polarization to scattering. Actually, when you have circular polarization, you can see your peaks more intense than linear ones.
dear Arezoo Zarei Thanks for your reply, In the case of the larger particle there will be loss due to high multipolar contributions and you are right that bigger the particle more it has the CDOP. But my question is that from LDOP we can sense the scattering modes (magnetic contribution, magnetic modes) but what is the relation of CDOP to the multipolar modes??? Any equation??? Like in case of LDP at 90 we have relation,

with the same idea into mind as in above paper can we relate or develop an expression to the scattering modes lets assume if the particle is comparable to wavelength?
