摘　　要：文中提出了一种基于阻抗变换槽线的三维超宽带微波吸收体设计方法,该设计采用多节切比雪夫匹配槽线结构和薄膜电阻,有效解决了传统电路模拟吸收体设计方法中介质基板的介电常数和方阻值不连续性的问题。通过精确求解电路参数并映射到物理尺寸,实现了一套超宽带微波吸收体的通用综合设计方法。所提出的吸收体展现了显著的实用性和高效性,在电磁隐身中具有广泛的应用价值。In this paper a novel design method of a three-dimensional ultra-wideband microwave absorber based on impedance transformation slot line is introduced.The design utilizes a multi-section Chebyshev matching slot line transformer and thin film resistor,effectively overcoming discontinuity issues in dielectric constant and sheet resistance of the dielectric media in traditional circuit analog absorber design methods.By precisely solving for circuit parameters and then mapping them to the corresponding physical dimensions,a synthesis design method of ultra-wideband microwave absorber is realized.The proposed absorber demonstrates significant practicality and high efficiency.It holds extensive application value in the field of electromagnetic stealth.
