摘要：
A model of electromagnetic fields in the air produced by a horizontal electric dipole in seawater with variable conductivity is designed to improve the calculation accuracy of electromagnetic fields and the reliability of the electromagnetic wave propagation performance evaluation in layered seawater media. Further, a method for solving the electromagnetic field components using the direct global matrix is proposed. This study evaluates the stability of the direct global matrix and the source of the calculation error with the generalized reflection matrix. The results show that employing the direct global matrix for solving the electromagnetic field components in multi-layered media effectively eliminates the accumulation of errors, layer by layer; thus, improving the stability and accuracy of the electromagnetic field calculations in real marine environments. © 2021, Editorial Department of Journal of HEU.
