Input VSWR of profiled E -plane tapers
Electronics Letters, 1981 An efficient method for determining the input VSWR characteristics of waveguide E-plane tapers is presented. The taper profile is approximated by radial waveguide sections and the junction wave transfer matrices are derived applying field matching. The input reflection coefficient is easily determined using these matrices.

Simulation and Measurements of VSWR for Microwave Communication Systems
International Journal of Communications, Network and System Sciences, 2012 Nowadays, microwave frequency systems, in many applications are used. Regardless of the application, all microwave communication systems are faced with transmission line matching problem, related to the load or impedance connected to them. The mismatching of microwave lines with the load connected to them generates reflected waves.
