Propagation Characteristics in a Circular Waveguide for Feasibility Study of Terabit DSL

Due to the demand for higher data rates and greater download speeds by users increasing number of deployed devices providing content-rich data, new cost-effective technologies which utilizes concept waveguides over copper that can enable realization ofterabit DSL need be explored meet required demands. This paper presents propagation characteristics circular waveguide include reflection/transmission coefficient, attenuation coefficient surface current. The design simulation process have been carried out using CST Microwave Studios at frequency 100GHz 300GHz. is varied various radius length observe respective characteristics. Based on result, it shown reflection decreases with increase in below -50dB. Besides, frequency, transmission shows able achieve 100% (0dB) 200GHz length. Moreover, low about 0.0022dB/mm maximum current intensity 81.5556A/m. results obtained considered first step understanding terahertz range towards Terabit DSL.
