angle of incidence

n
1. (General Physics) the angle that a line or beam of radiation makes with the normal to the surface at the point of incidence

an′gle of in′cidence


n.
1. Also called incidence. the angle that a ray, as of light, makes with a normal to a surface at the point where the ray meets the surface.
2. (on an airplane) the angle, usu. fixed, between a wing or tail root chord and the axis of the fuselage.

All the set-ups are composed of a wooden canvas, in which the prototype has been assembled and allows the required movements for the validation under different angles of incidence, two pairs of horn antennas (for the aforementioned different ranges of frequencies) mounted in rotary platforms for the validation of the different angles of polarisation and a vector network analyser.
As a result, the low intensity of the longitudinal field has small rises at some proximity to the surface, but the intensity of the transverse field is higher at the surface and drops at some proximity for rather wide range of angles of incidence. The latter is shown in Figure 3.
For angles of incidence in the -15[degrees]/15[degrees] range, their efficiency lies between 24% and 44%, the maximal value being obtained with an angle of -7[degrees] (7[degrees]) for -1st (+1st) order.
The transmission spectra of TE and TM polarized waves for the binary structure at various angles of incidence and for [gamma] = 0.2 x [10.sup.-3] GHz are shown in Figures 2(a) and 2(b), respectively.
The baseline design and its simulated transmission for several angles of incidence are shown in Figure 1.
Negative (anomalous) shift values have been observed at the angles of incidence in the vicinity of [k.sub.x]/[k.sub.0] [approximately equal to] 0.3 (6 [approximately equal to] 17.5 degrees) (Figure 3(c)).
The measurements were performed at angles of incidence below the Brewster's angle in order to remove reflection from the back side of the substrate.
The integration variables [xi], [zeta] have the following meanings: [xi] = sin v cos [phi], [zeta] = sin v sin [phi], where v, [phi] are the angles of incidence of a separate spatial TE or TM polarized harmonics with the amplitude [G.sub.1] ([xi],[zeta]) and [G.sub.2]([xi],[zeta]), respectively.
