【 摘 要 】

The paper considers the protection of critical electronic equipment from an ultrashort pulse (USP) by means of modal filtering technology. Decomposition of the USP in a reflection symmetric meander line consisting of four cascaded half-turns is investigated for the first time. Quasi-static simulation of two half-turn connection diagrams has been performed. The output of the circuits shows the presence of negative polarity pulses, as well as additional pulses with time delay values non-multiple of per-unit-length time delays. It has been revealed that these values are linear combinations (arithmetic means) of per-unit-length time delays of the line modes.
