We have studied the possibility to design a compact polarization plane rotator of electromagnetic waves based on the structures with dihedral symmetry. Proposed structure allows rotation of polarization plane at arbitrary angles and has acceptable lo

A numerical algorithm for the analysis and optimization of broadband polarizers consisting of symmetrically placed rectangular ridges in a coaxial waveguide is developed. Because polarizer boundaries cannot be described in a single (cylindrical or Ca
