A reflector includes an electromagnetic wave lens and a reflecting surface; the method is characterized in that: the electromagnetic wave lens is a compression deformable electromagnetic wave lens as claimed in claim 1, and the reflecting surface is a coating or a film layer arranged on the outer surface of the outer layer.
9. A reflector as claimed in claim 8, wherein: the bottom of the outer layer body is connected with a balancing weight; the reflecting surface is a concave surface or an annular surface of a hemispherical structure; when the reflecting surface is a concave surface of a hemispherical structure, the reflecting surface is arranged on one side or the bottom of the upper part or the middle part of the outer layer body; when the reflecting surface is an annular surface, the reflecting surface is arranged in the middle of the outer layer body, the reflecting surface is arranged around the outer layer body, and the central axis of the reflecting surface is perpendicular to the horizontal plane.
