概要
- 論文の詳細を見る
A tunable metamaterial absorbers (MA) comprised of a new combination shaped metal elements printed on a dielectric substrate loaded with PIN diodes were demonstrated. Through biasing at different voltages to control the diodes, the reflectivity characteristics of the structure can be varied over the entire 2-18GHz range. A qualitative analysis by a simple visualization method is carried out on the parameters of the tunable MA. Both numerical calculations and microwave measurements have verified the performance.
