Omnidirectional Reflection Characteristics of Photonic Crystal
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 1
Abstract
In this paper the reflection characteristics of photonic crystal is observed. Under certain condition, one dimensional dielectric lattice displays total reflection of the incident light. The thickness of the layers, the refractive indices should be carefully chosen for better reflections. This will find application in photonic reflector mirrors. The simulation results show the reflection coefficient for different cases.The wavelengths which are blocked are said to be in photonic bandgap.The signal outside the photonic band gap are transmitted. It is possible to design photonic crystals to transmit a single frequency or to reflect a single frequency or signal with narrow bandwidth. Defects are introduced for improving the performance.
