Abstract

The optical transparency of the microwave absorber is always emphasized, the effect of uneven transmittance which affects the imaging was ignored, thereby hindering further window application. Under the limitation of using uniform film, an absorber using transparent conductive film is designed for good-visual perception inspired by the Jaumann screen. Through adjusting impedance matching of the structure, the proposed absorber achieves 90% absorption in the range of 9.4 to 26 GHz (fractional bandwidth 93.7%). Meanwhile, the proposed structure measures 76.6% transmittance and 0.37% haze, denoting the application potential. It is believed that the proposed design strategy promotes the practicality process of transparent absorbers.
