Abstract: The present work is a serious effort in providing a Comprehensive Technical Analysis and Overview of the Recent Theoretical and Experimental Advances in Metamaterials. The Talk deals with the analytical treatment, conceptual explanation and unique characteristics of Artificial Dielectrics in the form of Dual-band Metamaterial Absorbers. A Qualitative Review of the available experimental results for better understanding of the concepts has been given. The technical analysis of the theoretical aspects of Concepts and Characterization of the dielectric materials in the form of Photonic Crystals, their Band Structure, and Devices based on them, with Emphasis on Designing of Fibers, and Novel lasers with Nanostructures, and Plasmonic Photonic Crystals along with the modeling and designing considerations for maximizing the efficiency of some of such devices, has been done very briefly in order to give a comprehensive picture about the various aspects of such materials. Their role as Hydrogel Sensors in Medicine and Biosensors, has also been briefly mentioned. This invited talk is expected to be immensely useful for the Researchers and Designers in this novel evolving field, and also in choosing a direction for their Research work on Artificial Dielectric Materials.

Keywords: Artificial Dielectrics, Dual-band Metamaterial Absorbers, Spatial Light Modulators, and Dielectric Materials based Hydrogel Sensors.
