Modeling Signal Inputs with Ansys HFSS Using Wave Ports and Lumped Ports — Lesson 2

When modeling an electromagnetic structure, the accuracy of the solution solver is dependent on the input signal definition, also known as the excitation. This excitation can be defined as a port on the geometry model. Ports can define either an input signal or an output signal. Ansys HFSS is a finite element electromagnetic solver that provides several ways to excite the model geometry. The excitation signal can be defined as a power, voltage, or current source. The most common port types used are wave ports and lumped ports. This lesson details the key points for defining these ports along with their differences and uses.
