Özet

In this study, a new method is proposed to verify the estimated effective medium parameters which are extracted from the transmission and reflection characteristics of metamaterial arrays. For this purpose, transmission and reflection characteristics of a broadside-coupled split ring resonator (BC-SRR) array are obtained by using CST Microwave Studio (CST MWS) and effective medium parameters (εeff and μeff) are extracted from these data. The extracted parameters are fitted to the Lorentz model and Lorentz parameters are obtained. These Lorentz parameters are used to construct an equivalent dispersive homogeneous slab in CST MWS. In the last stage, the transmission and reflection characteristics obtained from BC-SRR array and from the newly defined homogeneous medium are compared and the extracted effective medium parameters are verified. © 2011 IEEE.
