The content of this work is related to materials which are one of the most important issues for the continuation of human lives. Indeed, it focuses on a special category of very recent invented materials [2000-2001] called metamaterials. These are engineered materials providing specific properties not easily found in nature. The goal of this work is to characterize thin sheet metamaterials (metasurfaces). Really, every material has different physical, chemical, thermal, etc. properties. They are modeled by quantities such as density, hardness, boiling temperature, electric conductivity, etc. Knowing these parameters help to select the proper material for a particular application. This work concentrates on the determination of electrical/optical properties of metasurfaces; i.e., surface susceptibilities. Determining these parameters help to predict the behavior of the proposed metasurface in response to an external electromagnetic excitation. By introducing an analytical model, two important types of metasurfaces are investigated; i.e., those with randomly positioned inclusions and those supported by dielectric substrates. These contributions are expected to have a high impact in the design of metasurfaces in future.
