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 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.
