Özet

A new metamaterial topology, called triangular-shaped single-loop resonator (SLR), is introduced with two distinct μ-negative (MNG) regions and one ε-negative (ENG) region over the S/C frequency bands. Transmission and reflection characteristics of the suggested subwavelength resonator are analyzed using full-wave electromagnetic solvers, Ansoft HFSS and CST Microwave Studio (MWS), to demonstrate the presence of four closely located resonance frequencies within the 3.3-5.1 GHz range. Effective permittivity and permeability parameters of the resulting composite medium are retrieved from simulated complex scattering parameters to verify the existence of fully developed MENG and ENG regions. Dependence of the resonance frequencies on the design parameters of the triangular SLR unit cell and on the presence of its gaps are also investigated in detail. © 2011 IEEE.
