Abstract :
In the millimeter- and submillimeter-wave regions, the optical principles for microwave device design are used [1] as losses in waveguide devices are unacceptably large. The optical principles of design constrain the possibilities to create the millimeter- and submillimeter-wave region element base similar to the waveguide element base. Therefore, each quasi-optical system and all its elements are specially developed when solving this or that specific problem. At the same time, in the millimeter- and submillimeter-wave regions, there are wider possibilities of the development compared with the optical one. First of all, this is connected with the possibility to use foamed dielectrics as the focusing element material. Owing to the material small density, losses for absorption of such a focusing element are small, and losses for reflection are practically absent. With all this, admissible discrepancies of its surface shape with respect to the given one are many times more than those for the reflecting phase corrector, what makes easier its manufacturing.
