The present paper is a serious effort in providing an extensive technical analysis and overview of the recent theoretical and experimental advances in metamaterials. The paper deals with the analytical treatment, conceptual explanation and unique characteristics of artificial dielectrics in the form of photonic crystals. 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 paper 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.
