“…Our radiators [6][7][8][9]13,14] were emitting waves of the USEMP sub-nanosecond duration in the frequency range 0.1-6 GHz and with an effective voltage potential ER = 20-400 kV. These impulse waves, as simulators of EM interference with a peak strength of 5-30 kV/m, were successfully used for testing electronic devices for EM compatibility or immunity to the EMI.…”

“…Examples of two types of successful HPEM sources with hyperband spectrums in electromagnetic (EM) pulse waves are in [2][3][4][5][6][7][8][9]. One type of such sources was developed in US laboratories, and it was based on using high-voltage monopolar pulsed generators, which excited the antenna of a half-reflector type (HIRA) with a large diameter (3.1 m in [2], 1.2 m in [3], and 1.8 m in [4]).…”

“…A large diameter was a necessary attribute of these antennae so that they effectively emitted EM waves with frequencies in the lower range of 0.05-0.2 GHz [2]. Mobile autonomous radiators with relatively non-large sizes (L~0.6 m) as the HPEM sources with hyperband spectrums were developed in our Laboratory of Powerful Electromagnetic Impacts of the JIHT RAS [5][6][7][8][9]. These radiators contained the ultra-wideband (UWB) antenna array with four short shielded transverse electromagnetic horns (S-TEM-horns), which were excited by high-voltage (HV) monopolar pulses from a semiconductor pulser, DC power source, and control unit.…”

An antenna array with short shielded transverse electromagnetic horns (S-TEM-horns) for emitting high-power radiation of ultra-short electromagnetic pulses (USEMP) has been created and researched. The antenna unit consists of an ultra-wideband antenna array with four S-TEM horns, with each connected to a two-wire HF transmission line, and these four lines are connected to an antenna feeder. This feeder is connected to a semiconductor generator with the following parameters: a 50 Ohm connector, 10–100 kV high-voltage monopolar pulses, a rise time of about 0.1 ns, FWHM = 0.2–1 ns, and pulse repetition rates of 1–100 kHz. The antenna array was designed and optimized to achieve a high efficiency of about 100% for the antenna aperture by using a 2 × 2 array with S-TEM-horns, with shielding rectangular plates for the return current. The transient responses were studied by simulation using the electromagnetic 3D code “KARAT” at the time domain and experimentally with the use of our stripline sensor for measurement of the impulse electrical field with a 0.03 ns rise time and a 7 ns duration at the traveling wave. The radiators were emitting USEMP waves with a hyperband frequency spectrum of 0.1–6 GHz. The radiation with an amplitude of 5–30 kV/m of the E-field strength at a distance of up to 20 m was successfully applied to test the electronics for immunity to electromagnetic interference.
