Operative center of the geophysical prognosis in Izmiran [PDF]

open access: yesAnnales Geophysicae, 2005
IZMIRAN was founded about 65 years ago with one of the goals of carrying out geomagnetic prognoses. More or less, this activity has been developed during its entire history, but about 6 years ago this aim became sufficiently feasible due to the ...

Design of a polarization selective surface for co‐channel interference suppression

open access: yesElectronics Letters, 2022
In this paper, a novel design of polarization selective surface (PSS) is proposed for co‐channel interference (CCI) suppression. By establishing a switchable doublet topology, two types of second‐order filtering responses with two transmission zeros are ...
