    Abstract:
    The indefinite medium slab for which the permeability component along the z-axis of propagation was negative, while other permeability and permittivity tensors were positive was discussed. It was observed from simulations and transmission experiments on the SRR lattice that the component of the permeability perpendicular to the SRR axes was -1 near 11.3 GHz. It was found that the permittivity of the indefinite media was isotropic and equal to unity and the principal elements of the permeability tensors were also unity. It was also observed that the results of substantial field enhancement was consistent with ray tracing and numerical simulations which indicated that indefinite material had the potential for lens structures.
