Example Embodiment
[0100] Example 1
[0101] According to the method of the present invention, a metal cylinder with a radius of 1 m and a height of 20 m is simulated. The frequency of the incident wave is 3GHz, the incident angle is (40°, 0°), a total of 43 modes are required, and the number of bus division line segments is 2200. The result is in good agreement with the original rotational symmetry algorithm, which proves the correctness of the method, such as Figure 5 Shown. The present invention also shows the changes in time consumption and memory consumption of the present invention. Table 1 shows the comparison between the calculation efficiency in Example 1 and the traditional method. From the table, it can be seen that the memory consumption and calculation time are both higher than the traditional method. It saves.
