The paper highlights the importance of using evolution strategy (ES) in investigating ultrashort pulse peak voltages in multiconductor structures of printed circuit boards (PCB). Trapezoidal ultrashort pulse propagation along the conductors of a real PCB multiconductor bus was simulated and, with ES, the whole ultrashort pulse duration was optimized using the criterion of peak voltage ...

The simulation of the ultrashort pulse propagation along the conductors of the microstrip C-section has been carried out when the losses in conductors and dielectric were taken into account and without them. The voltage extreme points have been obtained with using of 7 values of the half-turn length. The highest voltage maximum exceeds the amplitude ...

In this study, we describe the specific features of the near-field distribution of a uniformly
illuminated aperture. An analytical method based on physical optics in the time domain is used to calculate
the field intensity. The primitive impulse response function makes it possible to calculate the near-field
distribution of the antenna. The difference in the amplitudes of the ...

The paper presents the circuit diagram and the parameters of the cross-section for the model of the power supply (PS) bus of a spacecraft. The optimization of the duration of an ultrashort pulse (USP) exiting the PS bus was made by genetic algorithm(GA) for minimizing the voltage maximum along the PS bus. The GA optimization ...

The study proposes to improve the process of large-scale investigation of circuits with modal reservation demonstrated on the example of double-sided printed-circuit board (PCB) with polygons. The TALGAT software was used as a simulation environment. The five different portraits (values along the conductor) of N-norms were obtained for each of the three signals: trapezoidal ultrashort ...

Abstract— In this letter, we present a method of calculating the monochromatic field radiated from a uniformly illuminated aperture. We show that closed-form functions are available in the time domain, which lead to frequency domain results. The time dependence of the field is calculated as the derivative of the primitive impulse response function (PIRF) of ...

In this letter, we present a novel time-domain analytic
formula for the elementary radiator antenna pattern of a metal
plane surface with infinite conductivity. The formula is presented
as a function of time and the integration angle. The formula refers
to a flat metal aperturewithout regard to its shape.We also describe
a novel equation for the primitive impulse response function ...
