Spectral approach to filter synthesis in waveguide and quasi optical structures

The traditional problems of filtering acquire, in the millimeter (mm) wave range, a number of peculiarities, consisting first of all in increasing requirements on the accuracy of design and manufacturing components. This work describes the spectral synthesis, strong analysis and theoretical investigation of band-pass (BPF) and band-stop filters (BSF) in waveguides and periodic grating angular (BPFA) or frequency (BPFF) band-pass filters in quasi optical structures. All synthesis and analysis algorithms are based on rigorous mathematical models.
