前言闸流管波导开关、是一个柵极触发的热阴极气体三极管,它的中心电极起两个作用:使电磁波按TE_(10)模传播,并接受触发脈冲使其触发柵阴极之间的等离子区。当一个合适的触发脈冲使阴柵极放电时,由于板极和阴极之间存在高靜电位,该等离子区就被转移到內柵(波导)区,即叫做转換。这样,等离子区处在波导中心,它的密度相当高,几乎能夠反射全部入射的微波脈 Introduction Thyristor waveguide switch, is a gate-triggered hot cathode gas transistor, its central electrode plays two roles: the electromagnetic wave propagation TE_ (10) mode, and to accept the trigger pulse to trigger the gate between the cathode Plasma area. When a suitable trigger pulse discharges the cathode grid, the plasma region is transferred to the inner gate (waveguide) region due to the high electrostatic potential between the plate and cathode, which is called switching. In this way, the plasma zone is at the center of the waveguide and its density is very high, reflecting almost all the incoming microwave pulses
