Abstract:
1. An S-parameter calculation apparatus for calculating S-parameters of a single device having a length N times a certain length L, wherein N represents an arbitrary integer of value of 2 or more, the apparatus comprising: an input unit inputting the S-parameters of said single device having a length of L; a port position correspondence conversion unit converting the input S-parameters so as to correspond to preset port positions when said single device is connected; a S-parameter/T-parameter conversion unit converting said converted S-parameters to T-parameters; a calculation unit carrying out a matrix calculation using said T-parameters, repeating (N−1) times a process of calculating T-parameters of a single device having a length corresponding to the length of said single devices having a length of L sequentially connected and calculating T-parameters of a single device having a length of L×N; a T-parameter/S-parameter conversion unit converting said calculated T-parameters of said single device having a length of L×N to S-parameters of a single device having a length of L×N; and an output unit outputting S-parameters of said single device having the length of L×N obtained by said T-parameter/S-parameter conversion unit.
