The latter occurs for a broad range of incident wavelengths, covering the whole visible spectrum, and of incidence angles.
12.
And, FSS filters are even easier to design than waveguide filters since the incidence angle does not vary with frequency.
13.
The CEP is thus adversely biased by a wide error spread in a longitudinal axis ( due to shallow incidence angle ).
14.
X-ray reflectivity from a mirror surface at small incidence angles may also be used to generate long-period XSWs.
15.
However, even these two maxima only appear at definite incidence angles close to the Bragg angle, \ theta _ B.
16.
An unstable or divergent phugoid is caused, mainly, by a large difference between the incidence angles of the wing and tail.
17.
One phenomenon particular to the cross-flow fan is that, as the blades rotate, the local air incidence angle changes.
18.
The Littrow configuration is a special geometry in which the blaze angle is chosen such that diffraction angle and incidence angle are identical.
19.
However, for wider incidence angles " & alpha; " some light may be lost, as shown on the right.
20.
He reported that with the speedometer still off the scale he attempted to recover from the uncontrollable dive by adjusting the main tailplane incidence angle.
