Abstract
The present invention concerns an electrically thin microwave phasing structure for electromagnetically emulating a desired reflective surface of selected geometry over an operating frequency band. The microwave phasing structure comprises a support matrix and a reflective means for reflecting microwaves within the frequency operating band. The reflective means is supported by the support matrix. An arrangement of electromagnetically-loading structures is supported by the support matrix at a distance from the reflective means which can be less than a fraction of the wavelength of the highest frequency in the operating frequency range. The electromagnetically-loading structures are dimensioned, oriented, and interspaced from each other and disposed at a distance from the reflective means, as to provide the emulation of the desired reflective surface of selected geometry. Another aspect of the present invention is the use of the electrically thin microwave phasing structure for electromagnetically emulating a desired microwave focusing element of a selected geometry. Additionally, methods are provided for designing and manufacturing electrically thin microwave phasing structures for electromagnetically emulating desired reflective surfaces and focusing elements of selected geometry, which methods may include the use of computer-aided design and photo-etching techniques.
