Abstract

Rectangular waveguide is a very promising structure for different applications. It has some unique characteristics that allow for wide range of application including slow and fast light, metamaterial, low loss energy transmission, and sensing. The resemblances and differences between this waveguide configuration and metal-insulator-metal (MIM) are discussed in this paper. A Description of the guided modes and their operating band is also given. We also studied the characteristics of the fundamental TM-like mode of this structure for the first time. Its potential application in sensing and low loss energy transporting is also demonstrated. The effect of the design parameters on the performance of the rectangular waveguide is illustrated for different application. Slow light and negative refraction effects using this waveguide design using TE-like mode is also demonstrated. Different designs are proposed using this structure for these different applications. Square shape design allow for polarization insensitive applications which is one of the unique characteristics of the configuration.
