These experimental results confirm that the amplitude increases progressively with respect to the speed for all considered incident angles
Organic filters are alternate options to interference filters and do not have the same sensitivity to source incident angles
as interference filters do.
According to this setup, the source shoots towards RTP rays at desired incident angles
and the detector compiles the output of the RR element.
For the current stage of investigation, a uniform wind velocity profile with little turbulence is required for studying the sole effect of opening sizes and wind incident angle
It is shown that the absorptivity is kept well for a wide range of incident angles
for different polarizations.
The magnitude of the reflection coefficient from this medium as a function of the incident angle
is shown in Figure 3(b).
Consequently, Figure 6-Figure 8 mainly discuss the one-dimension incoherent power angle distribution changing with rain environment parameters, and the frequency, the polarization and the incident angle
of the incident wave.
As for the TM wave (in Figure 4(b)), reflectance bandwidth is obvious enlarged at incident angle
of 88[degrees], however, the high reflectance range of TM wave no obvious increase at incident angels of 30[degrees] and 60[degrees].
It is observed that for monostatic case, the RCS of the board is below - 18 dB with the incident angle
ranging from -90[degrees] to 90[degrees], and a prominent RCS reduction is almost obtained across the whole angle range.
BASF Corporarion has received a patcnr for a color effect material comprised of a platelet-shaped substrate sequentially encapsulated with a first layer which is highly reflective to light directed thereon and which is selected from the group consisting of silver, gold, platinum, palladium, rhodium, rurhenium, osmium, iridium and alloys thereof; and a second spacer layer which does not provide significant incident angle
dependent variable pathlength difference, the spacer layer is selected from the group consisting of chromium oxide, zinc oxide, zinc hydroxide, zirconium oxide, zirconium hydroxide, zirconium nitride, titanium nitride, iron hydroxide, polymethyl methacrylate, polyethylene tcrephthalate, and high density polyethylene.
To change the incident angle
, it is sufficient to rotate the sample about the vertical axis that pass through the center o, while using the second degree of freedom of the sample for adjustments.
Figure 6 shows the experimental results of the ACR as a function of wind incident angle
with different opening configurations.
