Abstract

A novel transparent microwave absorber is proposed in this paper. Fluorine-doped tin oxide glass, glass and monolayer graphene are applied as the reflector layer, substrate and absorbing layer respectively to form a Salisbury absorber. The performance of the absorber is measured by the rectangular waveguide. An improved equivalent circuit model is proposed to analyze the transparent absorber. There is a good correlation between absorption coefficients obtained from the equivalent circuit model, 3-D full wave simulation and measurement. As high as 95% incident power can be absorbed by using the proposed absorber.
