不同上升沿电磁脉冲对腔体耦合的研究

Research on the Different Edges of the Electromagnetic Pulse to the Cavity-coupling

利用CST研究了不同上升沿和脉冲宽度的电磁脉冲分别对腔体上开有不同形状(正方形、长方形、正六边形)孔缝的耦合效应规律,研究表明:随着脉冲上升沿和脉冲宽度的缩短,电磁脉冲含有的高频能量越丰富,对目标腔体耦合作用越明显.

The CST method is utilized to study the cavity - coupling rules that different pulse width and rising edges of the electromagnetic pulses put impact on the cavity - coupling of the joints,which own the different shapes （for example： square, rectangle, hexagon）. Research shows that： with the rising edges and shortened widths of pulses,the highfrequency energy in electromagnetic pulses is more abundant than before. Hence, the target cavity coupling is also more obvious.
