Abstract :
The mathematically rigorous least-squares boundary residual method is used to develop a reliable model of a symmetrical five-port waveguide junction that has an oversized central cavity loaded with metallic rod and dielectric sleeve. Tests on a prototype junction yield measured scattering-coefficient results that are in excellent agreement with the predicted values over the entire WR90 bandwidth
