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.

Hence, the reflection coefficient depends on the frequency of the incident wave, that for the interface between air and the first layer (z = 0) becomes,
It is concluded that the displacement technic is a valuable calculation method for positive voltage reflection coefficient. For negative voltage reflection coefficient the mutual resistance between upper layer and bottom layer segments are sometimes negative, and thus their physical meaning is not related with the concept of resistance.
The final result for the reflection coefficient for the electric line source above the material stack is in (2) is [H.sup.(2).sub.0] the zeroth-order Hankel function of the second kind and R is defined in (3).
Table 1 provides the listing of the number of mesh elements together with the degrees of freedom and the processing time taken to calculate the reflection coefficient of the unloaded sensor in the frequency range from 1 GHz to 4 GHz for 101 points using various COMSOL mesh options.
The complex reflection coefficient, and hence [PSI] and [DELTA], can easily be modeled given material parameters.
The numerical reflection coefficient, [[GAMMA].sub.num], is obtained at different receivers located at ([i.sub.s], [j.sub.s] + l) for 0 [less than or equal to] l [less than or equal to] 250 providing an angular study of the absorbing behavior.
provides the separation dependent part of the free energy of the electromagnetic field at temperature T in terms of the reflection coefficients [r.sub.i] (i = 1, 2) of the two interfaces.
Figure 8(b) shows the simulated (line 2) and measured (line 1) dependences of the squared absolute value of reflection coefficient for such a structure.
The reflection coefficient is generated using calculated K =0.3393 using Equation 6, and the plot between both the reflection coefficient starts with a similar trend and matches correctly.
Using the boundary conditions at the first and last sublayers we find the required reflection coefficient.
The resonant frequency was matched to 8.9 GHz with a reflection coefficient of -41 dB.
When the absorbing structures are considered, the diffraction coefficients in Zone B and Zone C are reduced by a rate equal to the reflection coefficient. Table 3 shows three different cases in the estimation of superimposed waves: Case A is the current configuration with vertical reflective structures and Case B and Case C are related to the design of dentated vertical seawalls in place of the existing seawall and quaywall for incident waves with [T.sub.0] = 4 and 9 seconds, respectively.
