Abstract: Aircraft windshield compesite glass with a transparent conducting film on it have high electromagnetic and optical properties. This thes is studies mainly its electromagnetic function, for example, the internal relations between the transparent conducting film and backscatter radar power, electromagnetic absorptivity and reflectivity. Also studied is the optical transmittance of the compound glasses, such as the optimal design of multi layered thin films. A rational coupling between the transparent conducting film and the compound glasses is proposed to improve its electromagnetic properties and so is a rational coupling between the thin metal film and multilayer optical films to improve the transmittance. The abovementioned optimal design of multi layered thin films was completed and some qualified specimens were made by sputtering and evaporating method. After a rational match with the compound glass, its oblique incidence backscatter radar power dropped 10dB and its optical transmittance came to 77%.
