Applications of Electromagnetic Bandgap Structure in Microwave Photonics

Abstract

Microwave photonics is the arena of research in the 21st century due to ever-increasing ultra-large bandwidth and the meticulous availability of data with very low cost. In this context, conventional optoelectronic devices are replaced by novel photonic counterparts, both in transreceiver design as well as devices and systems. The major objective of this replacement is to reduce noise by means of lower scattering, where photons are only responsible for propagation of electromagnetic wave. With introduction of novel materials, low-loss communication system can now be designed at beyond THz range, mainly due to the physical realization of electromagnetic bandgap structure. This chapter is extended towards plasmonics with the intension of making sensors for beyond THz applications.
