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.

According to Figure 2, the elliptic cavity and the parabolic reflector can be expressed as
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.
It consists of a conical transmission line structure feeding into and attaching to a parabolic reflector. Suitable loads are placed between the transmission line feed and the dish in order to reduce reflections and provide the matched load required of the BTW (balanced transmission line wave).
Reflectarray antennas combine the same features of parabolic reflectors and phased arrays providing a directive beam in a desired scanned angle.
When combined with Streamlight's deepdish parabolic reflector optics, the Super-Tac[TM] delivers a long-range targeting beam for perfect illumination.
The plane wave produced by a compact range is generated by a large parabolic reflector (see Figure 8).
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.
This horn is a promising candidate as a feed for parabolic reflectors. Therefore, the horn is analyzed as a feed for the parabolic reflector.
