Multiple scattering of ultrahigh frequency (UHF) electromagnetic waves by two argon plasma cylinders is investigated, rigorously applying the boundary value method. The results are verified and validated with the method of moments. Approximate expressions for the far field, taking into account the interaction between the plasma cylinders, are derived briefly after some mathematical manipulations. Numerical results are presented for the case of E-polarized UHF incidence with varied striking angles and different separation distances between the cylinders; comparisons of the scattering distributions are given in detail as well. It is found that the interaction between the plasma cylinders plays a non-negligible role in scattered energy redistributing, which is useful in the future research of intelligent plasma antennas.
