t-matrix s-matrix conversion

Hi All,

I got a big [Y] matrix in hand, say the dimension is 104*104 ports. Now I only want to calculate the 3-port [S] matrix, the information of analysis is

port_in = [101,102,103]
port_out = [0,0,104]
z0 = [50,50,100]

the special point here is 'port_out(3)=104', I don't know how to handle this non-grounded output port. in other words, how to extract the 3-port matrix from original 104-port matrix when there are some non-grounded output ports? can anybody just give me some help or just hint, please... :D?

thank you very much in advance.

best regards,
tenderne

please... any suggetion?

is the question too easy or too difficult? please, anybody help...

you can perform that conversion easily with matlab

Hi ksugahar,

thank you very much for your reply.

but I don't understand, do you mean that Matlab can handling converting [Y] to [S] with non-grounded output port? would you please provide more details? thanks a lot.

best regards,
tenderne
