A simple algorithm is presented for evaluating scattering parameters of a two-port network. This technique uses the indefinite admittance matrix to calculate scattering or any other desired set of two-port parameters.
introduction: the human skin is an active medium from the optical point of view. therefore, the diagnostic and therapeutic techniques employing light are increasing. current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. studies have shown that biological tissues, and in particular skin, demonstrate polarization...
In the present work the first and second order scattering amplitudes and the related phase were calculated in the charge transfer channel. The positronium formation, with the impact of molecular hydrogen ion, has been carried out using multiple channel scattering formulation and transition matrix. The calculation of differential cross section has been done by varying the scattering angle from 0...
optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 gevic
A method is presented to reduce the singular Lippmann-Schwinger integral equation to a simple matrix equation. This method is applied to calculate the matrix elements of the reaction and transition operators, respectively, on the real axis and on the complex plane. The phase shifts and the differential scattering amplitudes are computable as well as the differential cross sections if the R- a...

In the present work, the transition matrix elements as well as differential and total scattering cross-sections for positronium formation in Positron-Hydrogen atom collision and hydrogen formation in Positronium-Hydrogen ion collision, through the charge transfer channel by Two-Centre Close-Coupling method up to a first order approximation have been calculated. The charge transfer collision is ...
A theory is presented that allows the Mueller matrix for coherent scattering to be calculated for arbitrary magnetic fields, atomic multiplets, and scattering transitions (Rayleigh or Raman scattering). For the special case of a normal Zeeman triplet (a J = 0 → 1 → 0 scattering transition) a compact analytical form for the scattering matrix is given, which allows us to better see how the variou...
