Reflection Symmetric Meander Line Protecting against Ultrashort Pulses

The paper considers the protection of radio-electronic equipment by means of devices operating on modal filtration technology. The possibility of modal decomposition of an ultrashort pulse in the reflection symmetric meander line (ML) is analyzed for the first time. It consists of two individual turns, in which the conductors are connected pairwise at one end. The work presents the results of quasistatic simulation of the time response of three schematic diagrams of an ML with the length of l m. The results showed the improvement of characteristics in comparison to the reflection symmetric modal filter, namely an increased value of the time intervals between decomposition pulses in the absence of resistors at one end of the line.
