Abstract:
1. A reflector comprising a reflective surface; said reflective surface having a shape defined by a plurality of parabolic portions juxtaposing each other; each said plurality of parabolic portions being a parabolic curve determined by a center point, a focus, a focal length which is a distance between said center point and said focus and a central axis which is a line joining said center point and said focus; and said plurality of parabolic portions further comprising a reference parabolic portion and a plurality of non-reference parabolic portions, wherein said plurality of said center points are along a reference line which is not a straight line and said reference line and said foci of said plurality of parabolic portions lie on a reference plane; wherein each said focus of said plurality of non-reference parabolic portions is derived from said focus of said reference parabolic portion; wherein electro-magnetic wave generated from any said focus of said plurality parabolic portions is reflected by said reflective surface at a direction parallel to said reference plane.
