Why Terminal S-parameters? • Terminal S-Parameters – By default the S-parameters in HFSS are expressed in terms of incident and reflected complex amplitudes of waveguide modes (modal S-parameters) – In the multi-conductor problems (where multiple modes are propagating simultaneously) these modes can be converted to physical quantities directly related to conductors such as currents • Examples – Coupled lines on PCBs and Packages – Multi-pin connectors – The Terminal S-parameter option was added to HFSS so terminal currents and voltages could be simulated directly. (Without this option we would have to determine these combinations ourselves) © 2009 ANSYS, Inc. All rights reserved. 15 ANSYS, Inc. Proprietary
