Optical Properties of Negative Index Materials
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 3
Abstract
In this communication, the optical properties i.e. the reflection behavior of one-dimensional PCs containing left-handed materials (LHMs) are theoretically investigated. The left-handed materials (LHMs) also called negative index materials (NIMs) or double negative (DNG) materials are artificial composite with both negative permittivity and permeability . The effect of variation of refractive index and number of periodic layers on the reflection behavior of PIM-PIM and PIM-NIM structure is studied here. The reflection behavior is compared to the normal photonic crystal structure that consists of alternate layers of dielectric materials having positive index of refraction (PIM-PIM) and structure containing periodic arrangement of PIM and NIM. From the study, it is observed that the reflection band gap increases in PIM-NIM structure as compared to PIMPIM structure.
