A significant excitation of toroidal moments in cylindrically arranged dogbone metallic inclusions is validated and presented in this paper. The antiparallel poloidal currents excited on the front and back faces of the proposed cylindrical dogbone inclusions create strong magnetic field confinement at the center generating intense toroidal moments on the structure. The significant excitation of toroidal dipole moment causes an improvement in the scattering cross-section from the resonant system. The resonant mechanism is analyzed using the multipole scattering theory, and we used the scattering measurement techniques to characterize the structure experimentally in the microwave regime.

圆柱形排列的狗骨金属夹杂物中的环形偶极子激发

本文验证并介绍了圆柱形排列的狗骨金属夹杂物中环形力矩的显着激发。在拟议的圆柱形狗骨夹杂物的正面和背面激发的反平行极向电流在中心产生强磁场限制，在结构上产生强烈的环形力矩。环形偶极矩的显着激发导致谐振系统的散射截面有所改善。使用多极散射理论分析共振机制，我们使用散射测量技术在微波范围内通过实验表征结构。
