Abstract

Abstract: According to the numerical calculation of electromagnetic field under cylindrical coordinate, the conventional split field absorbing boundary is no longer applicable. The coordinate stretched perfectly matched layers (CS-PML) were applied in the two-dimensional stretched cylindrical coordinate system. The updating equations of Maxwell curl equations in CS-PML were derived by using auxiliary equation method. The simulation results show that theoretical derivation is correct. The reflection coefficient of CS-PML is less than -30 dB, and it is able to meet the precision demand of numerical calculation. Besides, the CS-PML was adopted to investigate the radiation characteristic of the monopole antenna fed by coaxial cable. And the near-field and far-field pattern were obtained. The investigation provides a new idea and reference for the numerical calculation of electromagnetic scattering and radiation problems.
