英文摘要: |
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. |
