Polarization transformer with combination of diaphragms and pins

Abstract

Recently, polarization signal processing has become widespread. It is used in satellite information and telecommunication information processing systems. One of the key elements of such systems are polarization conversion devices. The basic function of such devices is to transform the types of polarization. There are different designs of polarizers. The most common are polarizers in the form of ridged structures [1], polarizers with thin metal septum [2, 3], polarizers based on irises in the waveguide [4-6] and polarizers based on waveguides with posts [7, 8]. There are also designs of polarizers with irises in the form of thin slots [9]. But such constructions are complex. The most broadband and simple design is a waveguide polarizer based on irises.
