Related to Grazing angle: angle of incidence, Glancing angle

an·gle of in·ci·dence

1. the angle that a ray entering a refracting medium makes with a line drawn perpendicular to the surface of this medium;
2. the angle that a ray striking a reflecting surface makes with a line perpendicular to this surface.
Synonym(s): incident angle

angle of incidence

the angle at which an ultrasound beam hits the interface between two different types of tissues, such as the facing surfaces of bone and muscle. The angle is also affected by the difference in acoustic impedance of the different tissues.

2. Angle that a ray striking a reflecting surface makes with a line perpendicular to this surface.
Synonym(s): incident angle.

angle of incidence

the angle at which a body, object or vector is moving relative to another (e.g. a stationary surface or environmental factor such as wind), often prior to a collision. Example: when playing a snooker ball at a cushion, the angle between the ball's direction of travel and the cushion.

DRS is similar to SIMS, except the ion beam and associated detector are incident on the sample at grazing angles.
At small incidence angles, the discrepancies are not large, and the discrepancies become larger with the increase of incidence angles, which indicates the nonlinearity is very important for sea surface scattering at low grazing angles.
Third, due to the consideration of computational efficiency, the approximate scheme employed to evaluate the multi-interaction between the incident wave and maritime scene is still comparatively simple, which limits the model also beyond the applications on very small grazing angles.
