“…In high-voltage pulse technology, the solution of the problem of measuring nanosecond differences (first of all, fronts) of high-voltage pulses at different loads is relevant [1][2][3][4][5]. In the work, the results of which are presented in [6], a compact autonomous resistive shielded low-resistive voltage divider (ARSLVD) is developed and tested to measure the record amplitude-temporal characteristics of high-voltage pulses from a generator in an apparatus for broadband electromagnetic pulse therapy (ABEMPT). The generator design is described in [6].…”

If the generator in ABEMPT operated without the use of a sharpening of the pulse front, then the voltage divider transmitted the expected pulse shape, including its front (≈2.5 ns), without distortion.…”

Purpose. Determination of the possibility of using the developed autonomous voltage divider for measuring high-voltage pulses with sharpened fronts (down to 1 ns). Methodology. We use the technique to determine the division ratio of the divider using a calibrated oscillator and oscilloscope. To determine the rise time of the transition characteristic of the divider, we use an experimental technique based on a high-voltage pulse generator with a steep front and computer simulation using circuit program Micro-Cap. Results. Oscillograms of high-voltage nanosecond pulses with subnanosecond fronts are experimentally obtained using an autonomous resistive voltage divider. A computer simulation of the operation of the created divider in various modes is carried out. Originality. We have shown that an autonomous shielded resistive high-voltage voltage divider can have a rise time less than 1 ns. The values of the parasitic parameters of the divider, which lead to a distortion of the sharpened pulse front with a rise time of ≈0.1 ns, are established. Practical value. The divider can be used to measure the characteristics of highvoltage pulses with a steep front (up to 1 ns as the lower limit). References 7, figures 15.

Rectangular (2.5×2 cm2 ) antennas fastened to an end of a transmission line were pulse-excited by 0.5 ns rise time pulses for radiation of ultra-wideband signals. Wideband horn antennas were used for receiving the signals and wideband sampling oscilloscope was used for their visualization. The signals were registered in 1-5.6 GHz frequency range and had the quasiGauss envelope form. The plane antennas made of Cu, resistive Al, and resistive nanostructured Ni thin films on supporting polyethylene terephthalate of 100 µm thickness were used. It is shown that the radiation induced by pulsed excitation can be used to control parameters of resistive coatings, including nanostructured ones, during a deposition process. The metallic nanostructured thin films could be used to create plane radiating and receiving antennas having resistive elements and adapted for ultra-wideband signals. Ultra-wideband antennas with resistive nanostructured coatings, which have properties that can be changed by external electric or magnetic fields or by optical radiation, can be used for modulation of radiated pulses. Further experimental studies are proposed to elaborate metallic nanostructured thin films suitable to withstand possible damages induced by short high power electrical pulses.
