Summary:
Left Handed Material (LHM) is an artificial material whose properties are determined by the structural arrangement of unit cell in a periodic array rather than the chemistry of the material it is made of. The possibility of negative effective permeability of a magnetic structure was first reported by Pendry et al [1]. To enhance the value of negative permeability, a number of inclusion was suggested by Roy et al[2] that resulted in the multiple split ring resonators (MSRR). They also made a comparative study of MSRR, SR(Spiral resonator), LR(Labyrinth resonator). Following the basic resonator structure J.D.Baena et al [3] proposed two structures: the so called two turn spiral-resonator (TTSR) and, non bianisotropic-spiral-resonator (NBSR). We derived the analytical expressions for the negative permeability of TTSR and NBSR structures which is not available in published literature. Our analytical results have been compared with commercially available FEM based simulation software(Ansys-HFSS). The approach is to establish the e.m.f. equation of the structure and from that we derive the effective relative permeability (μreff) of the particular magnetic inclusion structure and then do parameter extraction studies via simulation.
