Electromagnetic Scattering Characteristics of Metal Arc-Shaped Plate with Different Curvatures Under Underwater Magnetic Dipole Illumination

In marine environments, metal cylindrical shapes are quite common, such as underwater oil and gas pipelines. At the same time, due to the complexity of the marine environment, the pipelines may experience certain damages, which can cause their shape to transform into an arc-shaped plate with a certain curvature, rather than a closed cylindrical surface. We will study the degree of damage by converting it into arc plates with different curvatures, and use the method of moments to calculate their electromagnetic scattering characteristics, subsequently summarizing their scattering properties.
