摘要

Based on the vectorial structure of an electromagnetic wave,the analytical and concise expressions for the TE and TM terms of a vectorial plane wave diffracted by a circular aperture are derived in the far-field.The expressions of the energy flux distributions of the TE term,the TM term and the diffracted plane wave are also presented.The ratios of the power of the TE and TM terms to that of the diffracted plane wave are examined in the far-field.In addition,the far-field divergence angles of the TE term,th...
