driven terminal is a concept coming from circuit theory.The excitation is like the source in the circuit theory to drive a node(terminal).
driven mode is one concept from EM theory: wave propagation in guide structure only in some predetermined propagation mode which is decided by physical dimension.
connect the soures to the each terminal will excit several different mode.
Driven Modal Solution
Choose the Driven Modal solution type when you want HFSS to calculate the modal-based S-parameters of passive, high-frequency structures such as microstrips, waveguides, and transmission lines. The S-matrix solutions will be expressed in terms of the incident and reflected powers of waveguide modes.
Driven Terminal Solution
Choose the Driven Terminal solution type when you want HFSS to calculate the terminal-based S-parameters of multi-conductor transmission line ports. The S-matrix solutions will be expressed in terms of terminal voltages and currents.
Choose the Eigenmode solution type to calculate the eigenmodes, or resonances, of a structure. The Eigenmode solver finds the resonant frequencies of the structure and the fields at those resonant frequencies.
