Therefore, it is expected that, for a given S-matrix, a critical parameter [[beta].sub.c] exists, which controls the existence or not of a social structure.
where [GAMMA] is reflection coefficient matrix, c is excitation matrix and [S.sub.d] is meander DL detailed S-matrix. Primitive sub-matrix elements in the main and adjacent diagonals of detailed meander DL S-matrix is determined according to empirical formulas [15].
(18) and the S-matrix definition [[[b.sub.i]] = [S][[a.sub.i]], we can have
Several significant parameters in S-matrix of the nonlinear component are extracted through measurements.
All possible generators of supersymmetries of the S-matrix. Nucl.
Each element of the S-matrix is [S.sub.i,j] = [b.sub.i]/[a.sub.j] a ratio of a wave [b.sub.i] either reflected from or transmitted through the structure to the incident wave [a.sub.j] The waves are defined as a simple but very important transformations through voltage and current at a port i: [a.sub.i] = 1/2[square root of [Z.sub.0]]([V.sub.i] + [Z.sub.0] x [I.sub.i]), [b.sub.i] = 1/2[square root of [Z.sub.0]]([V.sub.i] - [Z.sub.0] x [I.sub.i])
Non-invertibility of the S-matrix based watermark embedding is demonstrated in Figure 16.
A matrix A [member of] [R.sup.nxn] is called symmetric diagonal plus semiseparable (1) or S-matrix if it has the form
Upon calculating the radiative corrections with the fields, masses, and coupling constants renormalized within the OMS renormalization scheme, the UV divergencies occurring in the loop expansion (of propagators as well as S-matrix elements) are absorbed in the infinite parts of the renormalization constants.
However, this provided the opportunity to construct an S-matrix, which makes use of the reflection coefficients and retains information on the transmission behavior of the device.
