Based on the basic electromagnetic theory, the three-dimensional electromagnetic scattering problem in the uniform conductive half-space frequency domain is studied in detail. The Fredholm equation is solved by the tensor Green’s function, and the anomalous body is divided into a series of cubic elements. The integral equation is transformed into the matrix equation The electric field and the magnetic field are calculated at any point in space. In addition, examples are given and compared with foreign results to prove that the calculation method used by the author is correct and the algorithm is fast.
