AI Technical Summary
When existing electromagnetic pulse generators use cable transmission lines, they suffer from problems such as uneven field strength distribution, high energy loss, difficulty in impedance matching, and low durability. This results in poor repeatability of test results and insufficient waveform fidelity, making it difficult to meet the requirements for high precision and stability.
A highly uniform electromagnetic pulse metal plate transmission line is adopted, including a carrier frame, pulse source system, terminal load and electromagnetic pulse fiber optic measurement system. A stable frame is formed by support columns and keel. Combined with the specific structural design of the upper and lower pole plates, edge effects are reduced. The electric field distribution is optimized by utilizing the material and geometric parameters of the metal plate to achieve impedance matching stability and accurate signal acquisition and transmission.
It improves the uniformity of electric field distribution, reduces high-frequency energy loss, stabilizes impedance matching, enhances the repeatability and durability of test results, and provides reliable support for simulating strong electromagnetic pulse environments.
