Provided is an S parameter derivation method for an electric network, the method capable of calculating an S parameter of the entire network including an asymmetrical network accurately in a short time. A first S parameter of a first network (60) having an input port and connection ports is prepared, a second S parameter of a second network (4) is measured, and an entire S parameter of an entire network (66) in which the second network (4) is connected to the connection ports of the first network (60) is calculated. Using, as an unknown value, a parameter corresponding to a dummy port among virtual T parameters of a virtual first network (62) obtained by converting the first network (60) into a symmetrical network by adding dummy ports to the input port side of the first network (60), and as an S parameter of the entire network (66), the entire S parameter corresponding to the input port among virtual S parameters of an entire virtual network (68) in which the second network (4) is connected to the connection ports of the virtual first network (62) is calculated. |
