The polarization and absorption character of the sequentially connection of the heterogeneities of the same type

The common theory of the multilink waveguide and quasi-optical filters of the UHF range and millimeter waves has been developed in previous works. The technological inaccuracy, which is inevitable in practical devices, causes a serious change in the operational characteristics. In particularly, defects in the periodicity influence to a degree the band and resonant selection. The analysis of the influence of such defects on the device characteristics allows one to expand the functionalities of the multilink selective systems.
