parabolic reflector

[¦par·ə¦bäl·ik ri′flek·tər]
(electromagnetism)
An antenna having a concave surface which is generated either by translating a parabola perpendicular to the plane in which it lies (in a cylindrical parabolic reflector), or rotating it about its axis of symmetry (in a paraboloidal reflector). Also known as dish.

parabolic reflector

A light reflector whose surface is a paraboloid, i.e., a surface generated by rotating a parabolic section about its axis; if a small light source is placed at the focal point of the reflector, the reflected light will be concentrated in a nearly collimated beam parallel to the axis of the reflector.

Recycling parabolic reflectors or dishes for use in parabolic mirror research/experimentation has been gaining popularity both in the scientific community and among STEM-education-savvy teachers.
Therefore, the only possibility to introduce Fresnel diffraction into the microwave reflector antenna market is to study other kinds of applications where parabolic reflectors can not be competitive.
It consists of a conical transmission line structure feeding into and attaching to a parabolic reflector.
Generally, the reflectarray transforms the spherical wave emanating from the feed into a plane wave at the output, like conventional parabolic reflector antenna.
The alternative of a polarization-twist system, in which a fixed horn and parabolic reflector illuminate a mechanically tilted flat reflector, appears in some Russian, French, and Israeli systems.
Irradiation uniformity is guaranteed by a parabolic reflector chamber with the Xenon lamp in focus, instead of utilising a rotating specimen holder.
Therefore, the horn is analyzed as a feed for the parabolic reflector.
The high-impact lens features a parabolic reflector to maximize light output.
