Abstract

This paper addresses the problem of strong electromagnetic scattering from traditional diamond-shaped/cylindrical support rods in electromagnetic testing. Low-scattering optimization research is carried out based on finite integration software CST (Computer Simulation Technology) simulation. The scattering mechanism is analyzed by combining geometric diffraction and traveling wave theories, the "convex" water-drop-shaped cross-section is optimized, and a segmented coarse-fine alternating cylindrical structure is designed to disperse the scattering field. Simulations show that the designed water-drop-shaped cross-section segmented support rod has lower scattering intensity in the target frequency band, with significantly reduced scattering in high-frequency bands compared to traditional structures.
