knife edge effect
In electromagnetic wave propagation , a redirection by diffraction of a portion of the incident radiation that strikes a well-defined obstacle such as a mountain range or the edge of a building. (188 ) Note: The knife-edge effect is explained by Huygens' principle, which states that a well-defined obstruction to an electromagnetic wave acts as a secondary source, and creates a new wavefront . This new wavefront propagates into the geometric shadow area of the obstacle.
