Abstract :
Nonspecular effect of a microwave beam associated with totalreflection(TR) is investigated by means of establishing ray model and angular spectrum representation. These approachs predicts the existence of not only a well-known Goos-Haumlnchen shift(GHS) but also a focal shift. The focal shifts are evaluated at a single dielectric interface, and approximate expressions are derived. At last, we conclude some properties as to the focal shift based on numerical analysis.
