Study on High-Power Microwave Power Protection Characteristics of Plasma Column-Ni-Zn Ferrite Structure Array Model

This paper mainly studies the absorption characteristics of high-power microwave (HPM) by plasma. Based on the plasma fluid method, the protection research of plasma array structure to HPM is proposed, and the influence of plasma on HPM transmission at different times is analyzed. It takes a certain amount of time for the plasma to accumulate to have a shielding effect on the HPM, during which the HPM can pass through the plasma layer in a very short time, causing power leakage. Based on this, the plasma column array structure combined with Ni-Zn ferrite structure is constructed, which can not only prevent power leakage, but also enhance the absorption and reflection of HPM, greatly improve the safety of the rear equipment, and provide effective guidance for the protection of plasma technology in the microwave field.
