The backward scattering becomes weaker as long as the frequency increasing, because the smaller wavelength may enable more EM energy to propagate through the plasma cylinder array.
In other words, the higher frequency enables more EM energy pass through the plasma array, which will results in weaker backward scattering as shown in Figure 5(a).
In short, a higher frequency or larger separation enables more EM energy pass through the inhomogeneous plasma cylinder, while the backward scattering width becomes smaller.
The scattering distributions (especially the backward scattering distribution) of the products are critical for identifying the abstraction pathway.
3 is that the backward scattering component exhibits a discrete speed distribution.
This weak rotational excitation is indicative of the collinear transition state that is expected for the abstraction pathway; the observed feature of backward scattering is rather similar to that of F([sup.
The results are analyzed by both the backward scattering time-of-flight profile of detectors (with different source-detector spacing) and the spatial sensitivity profile.
Brain activity is measured by recording the backward scattering profile in this study.
It is shown that with the increasing of the radius of the cylinder, the specular coherent scattering changes slightly, while the incoherent scattering at non-specular region increases evidently, especially at the backward scattering direction, as the coupling scattering between the target and the rough surface increases simultaneously.
theta]] for bare PEC scatterer is obviously large (more than 15 dB) in the forward and backward scattering region (green dashed line near the top and bottom regions).
Numerical simulations show that although small forward scattering can still be noticed, the cloak effectively reduces the backward scattering of the object whose radius is four times that the thickness of the cloak shell.
