Port and its terminal line in HFSS

Hi, there

Can anybody here give me a clear explaination or referrence on the difference between the Wave port and Lump port ?

Also, what is the purpose of Terminal line ? why do i have to tell HFSS the line? what is the relation between these lines and the Excitations?

Thanks a lot

I think Lump port enternal exsitation port and aplay for any mode and may use tow or more, but Wave Port only one port and aplay for TEM mode.
