On possibility of creation of millimeter and submillimeter waves element base on the basis of foam-dielectric lens transmission line

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.
