Abstract
The evaluation of electromagnetic material parameters from metamaterial structures has received much attention in the literature. Among others, one method is to retrieve the material parameters from the reflection and transmission measurements of the sample material. It has been found that the electromagnetic material parameters depend on the angle of incidence. Although based on the Nicholson-Ross-Weir technique, the proposed extraction technique has no limitations on the angle of incidence. The proposed extension of the NRW extraction technique is used to study a fishnet structure fabricated by nanoimprint lithography. Silver (Ag)- Magnesium Fluoride (MgF2) - silver (Ag) was deposited on the thick PMMA layer before directly imprinted by a stamp. The effective material parameters have been found to characterise the imprinted fishnet structure.
