The isolation is near to 50 dB over the frequency range up to 50 GHz for the beam width
of 40 [micro]m.
As is shown in Figure 2, the beam width
of control laser decreases with the increase of [D.sub.2].
However, there are only a few studies on the wide beam of DRA in the published literature [8, 9], and in these papers, except for the good performance of the beam width
, other performances such as impedance bandwidth and the size of the antenna are unsatisfactory.
Finally, the effect of beam width
on shear strength is linear as indicated by trend lines for all models except the ANNs model which showed a lower increase rate beyond 700 mm width.
Bazant and Oh  based on their experimental results, suggested to use a minimum beam width
of three times maximum aggregate size (da) used in testing, as the width of fracture process zone of the concrete is three times maximum size of aggregate.
Compared with LTC-PCMS, the new multifunctional MS enhances the gain and decreases beam width
of the antenna in 3dB AR band of 9.12-10.2 GHz.
There are plenty of high-tech bells and whistles, like Active Room Compensation technology, which adjusts sound output to the composition of the room (including furniture placement and your own position relative to the speaker), and Beam Width
Control, which lets you direct the sound to a specific spot--or let it blast from all 360 degrees.
The BeoLab 90 offers unique Beam Width
Control, which enables to change the width of the sound beam to suit different listening situations.
The unusual thing I did was replace the two landing lights (10-degree beam width
)--both in the nose of the cowling--with HID taxi lights (30-degree beam width
.) I wanted the wider beam because my problem with night flying was not landing, but it was finding those pesky taxiway exits from the runway.
"Analogous to nanoscale spotlights, the cubic antennas focus light with precise control over direction and beam width
," added Sikdar.
. In order to measure the effective vertical width of the beam that starts from the cone, appropriate measurements were performed by means of a diode laser and a screen.
