摘　　要：基在自由空间中以均匀平面波斜入射到二维缝隙的导体平板为模型,通过等效原理以及近似的贝塞尔函数推导出了缝隙的近场散射公式,并进行了相关的仿真。并以3G和6GHz的电磁波照射到连续的导体板以及其中间开有0.0127m缝隙时的两种情况作对比,分析了在不同频率下缝隙对于近场散射所造成的影响、磁场分布的周期长短以及对于波谱能量的分布变化。Near-field scattering of 2D slot on the conducting plane was established due to the equivalent theory and approximate Bessel function and the simulations were conducted. Through the comparison between the no slot planar and slot planar illuminated by the 3 GHz and 6 GHz microwave, the effect of near--field scattering the length of the period of the magnetic field and the distribution of the plane wave spectrum caused by the gap are studied completely.
