Radiation power of half wave oscillator antenna in magnetic anisotropic medium

摘要

Through the study of electromagnetic radiation problem in electric isotropic and magnetic anisotropic medium, in magnetic anisotropic medium, the existing work has derived the expression of the field intensity and the magnetic induction intensity, radiated by half wave antenna, and then in magnetic anisotropic medium, the expression of half wave antenna radiation energy density has been derived. Then, on this basis, we derive the expression of half wave antenna radiation power in magnetic anisotropic medium. The radiation power expression reflects radiation power is associated with a magnetic anisotropic media. When the medium is isotropic, the results coincide with the expected results, and the correctness of the derived results is verified. The results of this paper can be used to predict the radiation effect of half wave antenna in magnetic anisotropic media, and provide a theoretical reference for determining the radiation power of half wave antenna in magnetic anisotropic media.
