Class IV Gas-sands for which the

reflection coefficients decreases with increasing offset.

reflection coefficients [1].

The

reflection coefficients R are 1-[[rho].sub.sk]/[[rho].sub.0], where [[rho].sub.sk] and [[rho].sub.0] are the SW average amplitudes at x = 225-255 nm for the case with ([[rho].sub.sk]) and without ([[rho].sub.0]) the skyrmion.

The first order

reflection coefficients [r.sub.1] and [R.sub.1] are obtained after evaluating the integrals given in relations (3.5) or (3.6) for x [right arrow] -[infinity], and then comparing the behaviour of [[phi].sub.11](x,y) or [[phi].sub.21] (x,y) with relation (3.3) or (3.4).

In Figure 4(a), it presents the simulation result of the

reflection coefficient, [S.sub.11] by varied CRS on the ground-plane.

reflection coefficients on the inclination angle.

The fitness function is the summation of

reflection coefficient values from 2 to 6 GHz band's frequencies.

The model in [13] provides the waveforms of transmitted field, transmitted field beyond the cylindrical slab, that is, the cloaked object, transmission coefficient,

reflection coefficient (calculated by subtracting transmission coefficient from unity), and the real and imaginary components of the refractive index.

Similar to Figure 3(a), all curves of

reflection coefficients have two troughs.

Three relationships (1, 2 and 3) were developed between

reflection coefficients values from seismic data and well data.
