In this paper, an experimental study is performed to realize the electromagnetic properties permittivity (ε r ) and permeability (µ r ), of a solar panel substrate with SRR inclusions.The proposed study is conducted for the modern wireless communication applications. The solar panel structure is based on a flexible layer of PTFE. The SRR structure is constructed from two concentric rings of three periodical unit cells in their lattice. The substrate layer, based solar panel, properties are measured using a modified Nicholson-Ross-Weir formulations (NRW) to retrieve ε r =ε r '+jε r " and µ r =µ r '+jµ r " from the measured S-parameters. The Finite Integral Technique (FIT) simulations based on CST MWS software package formulations is invoked to evaluate the S-parameters based on the retrieved ε r , µ r and compare them to their relative measurements. Next, a PTFE sample is used to validate the proposed technique. It is found that the properties of the PTFE sample are quite relative to those published in the literature where ε r =2.07+j0.001 and µ r =0.999+j0.0001. Finally, an excellent matching is realized between the measured and simulated results.
