Abstract

The transparent composite metal dielectric material consists of two inducing layers and one functional layer between the two inducing layers and features that each inducing layer consists of two layers of different transparent dielectric film and the two inducing layers may have different optical thickness. The function layer may have doped inducing layer material to form multiple quantum well structure. By means of multiple reflection and quantum well-like resonant effect, the composite material anti-reflects the electromagnetic wave in required wave band while reflecting electromagnetic waves of other wavelengths. The present invention may be used as windoe material or transparent body material a well as in producing metal semiconductor photoelectronic detector and other relevant device.
