磁場強(qiáng)度矢量與磁極化二元相乘計算模型 ,求解磁極化率張量。有文獻(xiàn)資料。 A tomographic metal detection and characterisation system has been designed and built with the intention of recovering detailed information about magnetic and/or conductive objects within the detector space. This information is gathered as a result of a “walk-through” scan of a candidate in the same manner as would be expected at a typical security metal detector archway. Following the passage of the candidate, the system uses measurements from an array of coils to calculate the polarisability tensor, which is considered to describe the low frequency electromagnetic characteristic of a small metallic object when it interacts with a magnetic field. The tensor is known to vary according to the excitation frequency of the applied magnetic field, however in this system only a single frequency measurement is considered. In addition to the magnetic polarisability dyadic tensor the position of the perturbation is also determined as a product of the inversion algorithm. 另有紅包答謝! |

張量磁化率: M_{i} = \chi_{ij} H_{j} 其中,下標(biāo) i 和 j 指的是向量沿著某個坐標(biāo)軸的分量(例如,直角坐標(biāo)系的x-軸、y-軸和 z-軸)。 \chi_{ij} 是個二階張量,因次為 (3,3) ,描述因為外磁場施加于 j 方向,而產(chǎn)生的磁化強(qiáng)度在 i 方向的分量。 微分磁化率: \chi_{ij} = \frac_{\part M_{i}}{\part H_{j}} \chi_{ij} 是由𝑀 的分量對于 𝐻 的分量的偏導(dǎo)數(shù) |
