    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (52 KB)

    To increase the steepness of slopes of frequency response of waveguide filters with λ/4 coupling as resonant tanks, it is possible to use multiresonance diaphragms. A broad spectrum of the highest evanescent types of waves is launched on such diaphragms. For an isolation on the highest modes the additional resonance diaphragms with low-loaded Q-factor are fixed between resonant diaphragms. ... View full abstract»

    In the most analysis and interpretation problems, the segmentation procedure is the key one: it allows to separate an image into parts, which are informatively interpreted and correspond to different objects in the image analyzed. It is shown that approximating the Fourier transform spectrum module of the image allows to approximately increase the contrast by 3.5 times. The results of this researc... View full abstract»
