The angle between major and minor axes was fixed at 80[degrees].
Figure 8 shows [absolute value of ([S.sub.11])] of the proposed antenna for different ratios between major and minor axes. The other parameters of the antenna are fixed as shown in the caption of Figure 3.
One way to build the BFR is to first create a second ellipse (small_e) for which the major and minor axes are, respectively, [square root of [pi][a.sup.2]] and fnb2, where a and b are the major and the minor axes of the BFE.
To the right of the single, I placed a new double in which the major and minor axes of the inner and outer ellipse are reversed, which accounts for the fact that the space between the two ellipses is never parallel.
The diameters were obtained by measuring the major and minor axes (mm) of these images.
The average particle diameter was calculated in two ways: [D.sub.avg1], the average of the particle major and minor axes lengths; and [D.sub.avg2], a circle diameter with an area equal to the measured area of the dispersed particle.
In order to correlate the obtained information in the two orthogonal directions corresponding to the major and minor axes, a "K" indicator was established.
Any one planet, acting alone, would tend to distort the surface of the Sun into a prolate spheroid an ellipsoid having one major axis and two equal minor axes with one tidal bulge directed toward the planet and another equal bulge on the side of the Sun away from the planet.
Graham suggests that, because the molecular envelope is most dense along its major and minor axes, radiation penetrates farthest along lines at 45|degrees~ to these directions -- thus giving the distinctive fourfold symmetry.
By using these values, the ratios of major axes to minor axes of cells for both samples can be calculated according to the relation between [Delta][Epsilon] and the ratio of major axis to minor axis shown In Fig.
