Waveguide ports without sources are considered to be absorbing waveguide terminations in FEKO. i m wondering that if it is possible to consider those terminations as matched terminals ? simply : absorbing waveguide terminations = matched terminations ???? let's suppose a coaxial cable in which waveguide ports are considered. port 1 is connected to a waveguide source, where the port 2 is not connected. is it possible to say that the port 2 is connected to the characteristic impedance of the coaxial cable Z0=sqrt(L/C) ? where L and C are the p.u.l parameters of the coaxial cable Coaxial cable with waveguide ports
what is the best terminal geometry of a coaxial cable so that to get high accuracy results ? please see the following figures case 1 : case 2 : However, both results does not agree with TLM solution performed by FEKO. why? is the terminal connection geometry effect the results ??
