Embodiment Construction

[0035] In order to reduce the number of bus grids constituting the simulator, the total length of the wire grids and the number of resistors used as distributed loads, and ensure that the minimum value of the field peak value in the internal area of ​​the simulator will not decrease, this application adopts a special grid layout. Below in conjunction with accompanying drawing, the present invention is further described through embodiment.

[0036] In this embodiment, set the peak value V of the high voltage excitation source of the simulator s =3MV; the total number of wire grids constituting the single side plate of the simulator is N t , the height of the simulator is 10m; the half-angle of the double cone is 32°, so the distance between the plates on both sides of the simulator is 32m. The biconical impedance is 150Ω. figure 1 is the N pulled from the edge of the lower half of the circular cone bottom section y≤0 of one side of the cone to the ground on this side d Sche...

Abstract

The invention discloses a horizontally polarized bounded wave electromagnetic pulse simulator, a wire grid plate and a wire grid layout method. The present invention adopts a wire grid layout mode in which the number of bus grids pulled out from the edge of the upper half of the biconical circular section is smaller than the number of bus grids drawn from the edge of the lower half, reducing the number of bus grids constituting the simulator The use of: Through a specific layout, all the wire grids pulled out from the upper half edge of the biconical section are directly connected to the corresponding part of the wire grid pulled out from the lower half edge at a certain height from the ground , reducing the length of all wire grids pulled from the edge of the upper half of the biconical section. Compared with the uniform layout method, the current path flowing through the wire grid in the present invention is the shortest, so the electromagnetic wave radiated to the outside of the two polar plates through the wire grid is attenuated, which makes the minimum value of the field peak value in a certain area inside the simulator not decrease. , instead all increases.

Description

technical field [0001] This application mainly relates to a wire grid layout method of a horizontally polarized bounded wave electromagnetic pulse simulator. Background technique [0002] Horizontally polarized bounded wave electromagnetic pulse (electromagnetic pulse, EMP) simulator (BAILEY V et al published in "IEEE Trans. EMP simulators"; Zhu Xiangqin and others published in "Computational Physics" Journal of Computational Physics, Vol. 36, Page 691-698 in 2019, "Parallel Simulation Analysis of Large-Scale Horizontally Polarized Electromagnetic Pulse Bounded Wave Electromagnetic Pulse Simulator") due to the EMP effect Two EMP environments, "free space" and "near ground", have been extensively studied in experiments. The simulator is mainly composed of a double cone in the air, a symmetrical wire grid plate drawn from the edge of the circular cone bottom section of the double cone to the ground on both sides, and a resistor connected in series at the end of the wire grid....
