A novel type of radiating elements for slotted-waveguide arrays: offset cross slot s in a broadwall of a rectangular waveguide is put forward. Scattering and resonant properties of a single offset cross slot are analyzed using the Galerkin method with global sinusoidal basis. 提出了一种新的矩形波导缝隙阵列的单元形式-宽边偏置交叉缝,并采用全域正弦基Galerkin法对其散射特性和谐振特性进行了理论分析。
The experimental results show that the resonant frequency of FSS increases with the slot width, and the transmission ratio and resonant bandwidth is becoming greater. 实验测试的结果表明,缝隙宽度变大时,谐振频率升高,同时,FSS平板的透波率和谐振带宽变大。
In the X-band, the resonant conductance and the resonant length of the slot-pair as a function of frequency and slot displacement from waveguide center line, together with the resonant length as a function of wall thickness are calculated. 在X波段计算了缝隙对的谐振电导和谐振长度随频率与缝隙中心线偏离波导宽面中心距离的变化规律,谐振长度随波导壁厚度的变化关系。
The results show that the resonant effect, enhancement effect and the polarized property of electric field will appear during the HPM pulse into cavity, and that the coupling energy of square or circular slot is less than that of rectangular slot. 结论表明:HPM孔缝耦合存在共振效应、增强效应与极化特性;在孔洞面积相同的条件下,正方形或圆形孔隙的耦合能量小于矩形孔隙。
