Jones matrix for corner reflectors

Measurement Techniques, 1996
The Jones matrix for a corner reflector is obtained in explicit form. The structure of the reflector is equivalent to that of a system consisting of a linear phase element and a natural optical rotator.

Monolithic millimeter-wave corner-reflector antennas

International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990
A high-gain monolithic millimeter-wave antenna has been designed for 240 GHz. The structure consists of a long-wire antenna suspended in a longitudinal pyramidal cavity etched in a silicon wafer. This results in a planar traveling-wave antenna backed by a corner reflector. The array pattern is calculated by the method of images, and the element pattern

Pointing design and testing of corner reflector

AOPC 2020: Optical Sensing and Imaging Technology, 2020
The corner reflector is usually realized by fixing the corner cube prism through a specific structure, which is much easier to install and debugin practical application. As we all know, one of the most important uses of the corner reflector is that it can be used as a passive target marker for satellites and aircrafts.

Backscattering By a Dihedral Corner Reflector With Surface Deformations

Journal of Electromagnetic Waves and Applications, 2000
Aim of the paper is to analyze the electromagnetic scattering by a perfectly conducting dihedral corner with deformed faces. An accurate Physical Optics based model is developed to study the case in which only one face is deformed according to a parabolic law.

Integrated 222‐GHz corner‐reflector antennas

Microwave and Optical Technology Letters, 1991
AbstractA high‐gain monolithic millimeter‐wave antenna has been designed, fabricated and tested at 222 GHz. The structure consists of a traveling‐wave antenna integrated on a 1.2‐μm dielectric membrane and suspended in a longitudinal cavity etched in a silicon wafer.

Improved corner reflector antenna performance by using cylindrical reflectors

Proceedings of CEM 2002 - 4th International Conference on Computation in Electromagnetics, 2002
A design improvement for comer reflector antennas is presented based on the use of three cylindrical reflecting surfaces. A significant increase in antenna gain is achieved with almost the same directivity. The main benefit of this design is to enable the development of small and low cost antennas for radio communication links. (2 pages)

The design of the corner-reflector antenna

Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1959
The corner-reflector antenna has been investigated by Kraus and others.1,2 The mathematical expressions for the array factor as given in this earlier work are cumbersome, making it difficult to design such an antenna accurately. It is the purpose of this paper to overcome this difficulty.

A circularly-polarized corner reflector antenna

IRE Transactions on Antennas and Propagation, 1957
Unidirectional, circularly-polarized radiation may be obtained by tilting a dipole in a corner reflector. Inherent advantages of this antenna are the simplicity of both the construction and adjustment. The theory of images is employed to develop the basic theory of the antenna for the cases of greatest practical interest.

Optical Testing Of High-Quality Corner Reflectors

SPIE Proceedings, 1987
This article presents two techniques to test the quality of corner reflectors. The first technique uses an autocollimation setup while the second one is based on interferometry. Several corner reflectors were tested with both methods and the results indicate that the characteristics of a corner reflector as provided by the manufacturer are generally ...

FIELD OF A DIELECTRIC-LOADED, INFINITE CORNER REFLECTOR

Canadian Journal of Physics, 1958
A study has been made of the effect on the radiating properties of an infinite corner reflector of loading its apex with a section of a dielectric cylinder of polystyrene and of a material with a relative permittivity of 4. Calculations of the radiation resistance and of the far-field amplitude have shown them to be sensitive to the presence of the ...
