uW_S2P_DELTA — Calculate the determinant of an S2P file.
D=uW_S2P_DELTA(S)
tlist containing the S parameters.
vector. Value of the determinant according to the frequency list of the S2P object.
This function calculates the determinant of a S2P objet S as follow : D=S.S11*S.S22-S.S12*S.S21. The condition of unconditional stability is achieved when K greater than 1 and abs(D) lower than 1 with : K=uW_S2P_K(S) and D=uW_S2P_DELTA(S).
