摘要：

In this paper, we theoretically derive the local density of state (LDOS) in vacuum above a semi-infinite metamaterial. By using S-parameter retrieval methods, the obtained results of effective permittivity and permeability are employed to analyze the LDOS of metamaterial. It shows that p-polarization surface wave is the major contribution to near field radiation for electrical response, while s-polarization surface wave contributes most to near-field radiation for magnetic response. The study suggests a convenient way to control the enhanced near-field radiation.
