Left-handed Maxwellian behavior of natural Mica. (English) Zbl 1266.78014

Summary: The meta-material-like behavior of natural Micas are studied. This work makes an attempt to analyze the left-handed Maxwellian (LHM) properties of Micas. The investigations carried out on natural Mica specimen are with regard to optical reflectance, optical absorbency and DC current-voltage-characteristics (CVC). The optical reflectance of a Mica sheet with plane polarized monochromatic light shows a distinct difference compared with conventional theoretical results. The DC CVC also is measured with complete electromagnetic shielding. There exists a clear difference in DC characteristic for presence and absence of stray electromagnetic fields. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible spectroscopy (UV-VIS) analysis are also carried out for further analysis. The results obtained from the optical reflectance characteristics using polarized light indicate LHM behavior as it may be found in a meta-material. Micro-structural and electrical analysis shows the behavior of a nano-structured layered material.
