利用频域矩量法（MoM）算法对埋在有耗色散半空间中的导线的短脉冲平面波散射进行了建模，并通过傅里叶变换计算了时域散射场。此外，还计算了这些目标的复谐振频率。详细研究了埋线散射的现象学，并证明了埋线方向和半空间电学特性对时域散射场和目标共振的影响。>
A frequency-domain method-of-moments (MoM) algorithm is used to model short-pulse plane-wave scattering from a wire buried inside a lossy, dispersive half-space with the time-domain scattered fields computed via the Fourier transform. Further, the complex resonant frequencies of such targets are also calculated via the MoM. The phenomenology associated with scattering from a buried wire is investigated in detail, and it is demonstrated that the time-domain scattered fields and the target resonances depend on the buried-wire orientation as well as the electrical properties of the half-space. >
