“…In order to model these phenomena, one has to, first, ensure propagation of an EMP in the form of a transverse TEM mode and, second, create a partially ionized medium with controlled parameters along the path of EMP propagation. The first successful attempts to experimentally study transformations of the EMP waveform during EMP propagation in plasma were made in the USA in the 1970s using pulses, which had durations of about 1 ns, and pulse rise fronts of about 250 ps [18,19]. Within the framework of these studies, the concept of a double plasma-filled transmitting line, which maintained propagation of an EMP in the form of a TEM mode, was realized for the first time.…”

A large-scale coaxial line filled with the plasma of RF discharge has been developed for laboratory modeling of the effects of the interaction of ultrashort electromagnetic pulses (EMPs) with the atmosphere and the ionosphere in the KROT facility. The oversized coaxial line ensures pulse transmission through an ionized medium in the TEM mode, which corresponds to the polarization of the transverse electromagnetic wave in free space, and in uniform isotropic plasma. The coaxial line has a length of 10 m and a diameter of 140 cm. The processes of propagation of the nanosecond and subnanosecond pulses in this line, in vacuum and with plasma, have been simulated numerically.
