reflection The act or process of redirecting electromagnetic energy along a new path, using a conduc- tive surface or impedance discontinuity. At a surface, the angle of the reflection equals the angle of incidence, i.e., the angle at which the incident signal strikes the plane surface of the obstacle. At the extreme, the signal reflects back towards its point of origin. See also angle of incidence and refraction. 74570c18.qxd 9/12/07 12:39 AM Page 414 |
