This paper discusses our investigation into artificial structures called metamaterials. Metamaterials make it possible to achieve electromagnetic properties not existing in nature. The investigation focuses on the modeling, fabrication and testing of metamaterials at optical frequencies. The main purpose of this research is to identify a method to fabricate the artificial structures. We identify limitations in the fabrication process which are used to build the metamaterials. Measured reflectance data from fabricated devices is then compared with modeled data to identify limitations affecting the "as-built" figure of merit (FOM). Understanding the parameters which limit the FOM will lead to device fabrication improvements and ultimately to components suitable for optical applications such as optical surveillance systems.
