Frequency selective plate and method for producing same

摘要

The invention relates to a frequency selective plate having a radio wave transparent property. This frequency selective plate includes (a) a transparent substrate; (b) a mixture layer formed on the transparent substrate, the mixture layer containing a mixture of a metal nitride and Ag; and (c) Ag particles formed on the mixture layer, the Ag particles being two-dimensionally distributed on the mixture layer and being separated from each other.
