Figure 3 shows the angular width for the P wave radiation as a function of the parameter [bar.[lambda]]; it can be seen that the
angular aperture for the radiation field of P waves in general is less than that of S waves, which shows the importance of S waves in the fracture process material by detonating cylindrical explosive charges.
The
angular aperture [theta] of a possible secondary concentrator must be defined considering the position of all mirrors composing the solar tower plant.
The frequency range for the proposed model is f = 8 ~ 12 GHz with 401 frequency steps, the
angular aperture is [theta] = 0[degrees] to 360[degrees] with 1 degree angular step.
This paper illustrates the efficiency of the proposed beamforming and post-processing algorithms in terms of
angular aperture and target detection.
where [lambda] is the wavelength of light, n is the refractive index of the medium and [alpha] is half the
angular aperture of the lens.
In a divergent beam diffractometer these include the
angular aperture of the divergence slit, the width and axial length of the receiving slit, the
angular apertures of the axial Soller slits, the length and projected width of the x-ray source, the absorption coefficient and axial length of the sample.
