## re·flec·tion co·ef·fi·cient (σ),

a measure of the relative permeability of a particular membrane to a particular solute; calculated as the ratio of observed osmotic pressure to that calculated from van't Hoff law; also equal to 1 minus the ratio of the effective pore areas available to solute and to solvent.

If the interchanges DPS [left right arrow] DNG and ENG [left right arrow] MNG are made in all the layers except in the half spaces on the two sides of the multilayer structure (which is more realizable), then the reflection coefficients become complex conjugates and the reflected power remains the same.
Since the reflection coefficient is a direct indicator of efficiency, it is expected to appear in the equation.
In some actual industrial applications, we need to quickly estimate the reflection coefficient of the antenna rather than accurate measurement.
Using MathCAD[TM] (numerical solver) the roots that satisfied both transmission and reflection coefficient equations [100] can be calculated and drawn as shown in Figure 5.
The measured and calculated values of the reflection coefficients are matched using the Newton-Raphson algorithm to estimate the true value of permittivity.
However, only VES 8 to 10 had low to medium reflection coefficients having a linear relationship with their overburden anisotropy coefficients.
The stability criterion via a reflection coefficient is as follows [13]: a polynomial f(z) has all its roots inside the unit disk if and only if |[k.
