Abstract
- In order to design the scale model in a wide frequency range, a method based on the reflective loss is proposed according to the high-frequency approximation algorithm, and an example of designing the scale model of a plate-shaped absorber is given in this paper. In the example, the frequency of the full-size measurement ranges from 2.0 GHz to 2.4 GHz, the thickness of the full-size absorber is 1 mm and the scale ratio is 1/5. A two-layer scale absorber is obtained by the proposed method. The thickness values of the bottom and top layer are 0.4 mm and 0.5 mm, respectively. Furthermore, the scattering properties of a plate model and an SLICY model are studied by FEKO to verify the effectiveness of the designed scale absorber. Compared with the corresponding values from the theoretical scale model, the average values of the absolute deviations in 10 GHz∼12 GHz are 0.53 dBm2, 0.65 dBm2, 0.76 dBm2 for the plate model and 0.20 dBm2, 0.95 dBm2, 0.77 dBm2 for the SLICY model while the incident angles are 0°, 30°, and 60°, respectively. These deviations fall within the Radar cross section (RCS) measurement tolerance. Thus, the work in this paper has important theoretical and practical significance. [ABSTRACT FROM AUTHOR]
