Abstract The expression of dyadic Green s function for one and two cylindrical layers of chiral medium are derived by using the method of scattering superposition, for which the electric current sources are placed both inside and outside of a chiral cylinder and a cylindrical chirodome. Then the radiation characteristics of a point dipole antenna on the axis of the chiral cylinder and cylindrical chirodome are analysed. The results show that the polarized states of radiated fields can be changed by choosing the size of chiral cylinder or the thickness of cylindrical chirodome. Also, the expressions of dyadic Green's function given in thid paper can be directly use to analyse the radiation characteristics of cylindrical chirostrip antenna.

Key words： Chiral medium Chirality admittance Dyadic Green s function Method of scattering superposition Point dipole antenna
