Numerical electromagnetic simulator termination de-embedding technique

The authors report a novel approach whereby transmission-line end effects can be assessed by numerical simulation without recourse to the evaluation of the propagation properties of the line interconnecting the termination and excitation signal launch planes. As an example of the new technique, a microstrip open-ended line termination simulated by the finite-difference time-domain method is reported. The simulated results are compared with those obtained for the same structure but by a conventional numerical de-embedding scheme. The method presented is completely general and can be applied to any numerical electromagnetic field simulation method solving one-port or multiport networks
